I can find no reference in any of the books by Roger Freeman ( THE expert on the 8th.) to USAAF stations in the UK, in WW2, to being anything other than Station no xxx whilst under US control. Once taken over by the RAF they became RAF "whatever".
Whist I've been unable, at presenrt, to trace a source I'm sure that I've read that the post war naming of a US occupied station, as an RAF station, was nothing but a "figleaf" to try and divert or, at least, reduce attention from it's US occupation. There was quite a strong body of opinion post war which opposed the US bases on the basis that they made us a likely target for a Soviet attack.
