In the area of Toulouse you have GILL AIRWAYS in Agen and another school (I've forgotten the name) in Perpignan. But none of those schools have an aerobatic aircraft.
You've got too a school in Muret (LFBR) (one of my friend passed his CPL IR and FI). I don't know if they have an aerobatic aircraft, but you've got some airclubs on the airfield who have CAP10.
