The short answer is yes, they use the VAB and not the AMX10P.

Legion 'mech' infantry regiments are part of french light armoured divisions (now named brigades if I understood Sparfell correctly). Light armour divisons have/had their infantry in VAB's, heavy armour divisions (and mech infantry) have/had them in AMX10P's.

The info I have on this show's TO&E's from during the 80's. If and when the legion had tracked mechanised formations (with AMX10P's) before or after this I don't know.
Besides the units that are part of regular french formations the legion also has 'independent' regiments and groupings which can be equiped as the situation warrants. 'Heavy' mech legion units (with AMX10P's) are therefor a distinct possibillity (especially under hypothetical wartime conditions) but there are as far as I know no legion formations who have it as their integral transport.
Sorry if my earlier remarks a few weeks back were confusing on this.
