For examples of cloverleaf interchanges between two streets that aren't a part of their state highway system, a US route, or Interstate. I can think of two.
Shadeland Ave and Washington St on the east side of Indianapolis. https://goo.gl/maps/JHc3C1z5RTJChBWe6
Memorial Dr and Waugh Dr in Houston. https://goo.gl/maps/5pJeVkwAryd6D1xx6
There are also a number of interchanges in Washington, DC, that come close to this criteria, but none that I can find are complete cloverleafs.
It may surprise some to learn that Minneapolis has none of these currently, but it did have at least two historically where the Hennepin County 18 freeway had full cloverleaves with Rockford Road and Bass Lake Road in New Hope. County 18 became US 169 in 1988.

Washington St. was US 40, and Shadeland Ave. was IN 100, before 100 was decommissioned and the other highways were routed onto I-465. IIRC, that interchange was built before the adjacent leg of 465 was.

North Capital St and Irving St.
World Drive and Osceola Parkway in Walt Disney World.
^ With a couple extra ramps going into Hollywood Studios...
Does this count? (https://www.google.com/maps/@39.9789246,-74.1830573,393m/data=!3m1!1e3)
Sure, it's not grade separated... but it's a cloverleaf.
One of the routes is also a NJ 500 series county route.

I think whether the NJ 500 series routes are part of the state system is debatable, given that they're country routes. They're not in TravelMapping, either.

Doesn't really mean anything in the context of this thread. A number of state systems have not been completed yet in TM.
I recall seeing one in Baton Rouge LA. Don't remember if any sort of state route numbers were involved but hey, it's Louisiana and they will number anything...LOL! It struck me as a strange thing to see but the idea is good for connecting two busy streets. I would like to see more of them.

Are secret numbers disqualified? Northern State Parkway and Sunken Meadow Parkway/Sagtikos Parkway on Long Island.

I thought that everything that wasn't Mississippi was in active or preview by now?
In any case I personally refuse to consider anything signed with county route shields to be a state route. Anywhere.
In Seattle, 15th Ave W and Nickerson St / Emerson St just south of the Ballard Bridge isn't a cloverleaf but comes really, really close. None of those roads even used to be a state highway.

I have a really hard time calling that anywhere close to a full cloverleaf. For starters, it only has ramps on two of the four quadrants, and only one quadrant has a standard cloverleaf loop ramp.
It's a parclo, with some extra weirdness in the northeast quadrant to favor traffic exiting/entering 15th.
(It is a grade-separated interchange between two non-state highways though, which is still cool.)
Silver Spring and North Sherman Blvd in Milwaukee (https://www.google.com/maps/@43.1194424,-87.966221,794m/data=!3m1!1e3) should qualify. It's not a perfect cloverleaf - two ramps on the northbound side go to a side street to complete the interchange - but it operates like one.
Silver Spring is a surprisingly effective way to bypass downtown Milwaukee from the north. I used it frequently when driving between St Louis and Green Bay, especially before US 151 was four-laned. It has three other diamond interchanges where it is considered the through route - Teutonia, N 76th, and W Appleton. Appleton is the most surprising as it's also WI 175 (formerly US 41 ages ago).

County routes aren't part of the state highway system.
I remembered a real even closer-to-cloverleaf near where I grew up: Aviation Parkway and Airport Boulevard, just outside RDU Airport, Morrisville, NC: https://www.bing.com/maps?osid=b9aaec84-6b2d-4577-b152-6bf6743a16fa&cp=35.865447~-78.804917&lvl=16&v=2&sV=2&form=S00027 . Okay, it's missing ramps in one direction (WB Aviation - SB Airport has to turn on Trade Dr and go past the rental car facilities), but every other direction has a full interchange without stopping.

I used to live in Baton Rouge and I can remember several non-freeway full cloverleafs, but the ones I recall were all on US 61, aka the Airline Highway. The one you saw was not on the Airline?

Although its awkward, and does involve a neighborhood street, Washington & Arlington Blvd's (on the west side of Arlington Cemetery) is another DMV-area full cloverleaf between city streets. One of the routes is US-50, but its more of a city street (or perhaps an expressway) than a freeway. Washington Blvd is a sort of faux-freeway to the south, though I doubt Arlington County would consider it as such.
^ VDOT still maintains both routes (Arlington Blvd in both directions, Washington Blvd to the south as part of VA 27). VA 27 is considered freeway...US 50 is considered limited-access through Arlington County and into Fairfax but as you note is not a freeway.
