Rommel i'm sure used 88's in France,he saw thier worth as a big gun against armour but they were mostly not used as an ATG,very hard to get them down to a level firing position,until the gun carriage was redesigned and AP shells replaced the flak shells, that they became a more less dedicated ATG's we know of in No.Africa.
So i agree they were used in France yes,but not "expressly in a ATG role" as you say,more as a last ditch ATG with the inferiour flak rounds and mostly in the AAA role.
