If you log in using FR language then COHV should automatically pull up the list in French language.
For your information that list is saved in the domain PPIO_LISTTYPE.
Go to SE11 enter the domain PPIO_LISTTYPE and click on tab Value Range.
Make sure the language FR is installed properly in your system ( Contact your basis administrator or TCode SMLT and check the profile zcsa/installed_languages tcode RZ11 has atleast the letters DEF, D stands for German, E stands for English and F stands for French)
If you're logged in through English language but want to display in French, then I don't think it is possible without modifying standard code (changing the domain values), which is highly not recommended.
