I doubt it. The big airports have to speak English. The small airfields are not likely to be ramp checked and as its not an ICAO or EASA requirement to have non English language proficiency displayed on a Part FCL licence then they are not going to be able to enforce it. If you are stopped and are Level 6 French then you will have no problem explaining to them the facts!!
I got ramp checked at Biarritz last week and they were only interested in seeing that my CPL and medical were current and the aircraft documents not my language level.
You are worrying over nothing methinks.
