Travel from US to India via France on expired visa

Need advice. Does my spouse need valid visa stamped (US or France) while talking a flight from US to India via France.

Current visa status: My spouse is traveling to India for visa stamping. He got “change of status” from H4 to L1 individual in US thus he doesn’t have a L1 visa stamped on his passport but he has a valid I 797A till end of 2024. The only visa stamped on his passport is for H4 that too expired in feb 2021.

Transit visa is what he will need.
