“Excuse my French” is a common phrase meaning “excuse my bad language” (cursing). Ye plays off the fact that they are in Paris, France to excuse himself from “speaking French.”
“I’m in France” is a (sort-of) play on the phrase “When in Rome, do as the Romans do” (or, as Ye would probably say it, “When in Rome, do the Romans”). He’s saying that he doesn’t come to France that often, so when he does, he wants to live it up in Gallic fashion.

His modus operandi seems to be apology/realness/the obvious.
He recently tweeted about an alternate, after-the-fact meaning to this line:
