Yes, there are Court bags made in the USA. Here is a ebay link that was shared recently with some creed guides.
https://www.ebay.com/gds/Guide-to-Vintage-Coach-Hang-tags-and-Creeds-/10000000177697673/g.html? The bags that are on my radar tend to either have the creeds listed as they are in the 1970s - 1993 or the 1994 - 2000s (based on this guide).
I'm definitely not an expert (and these are not authenticated but I was trying to find listings to help), but I found an ebay listing for a Spectator Court (which I'm not sure if it is the same dimensions of the Court recently pictured here) and they have a catalog picture included that mentions a 1989 preview.

I'm not an authenticator, but I've actually seen some of these styles or similar ones with creeds that indicate made in Mexico, Costa Rica, Turkey, Hungary, and Italy. Here is an example of one from Costa Rica

I actually like the look of the Regina, Court, and Manor bags myself. Often I see many Court's listed as vintage
Coach Willis or just vintage Coach messenger or vintage Coach flap bag. Do you have a color in mind? I'm curious if the leather/feel is different depending on the year and country? For example, not sure if specific to Court, but I think I've read that some find the Costa Rica leather really nice. I would run by whatever bag you are interested in on the AT thread before you even consider bidding or anything (just to be safe you are getting an authentic bag).
