Looking at it logically and turning from the RAW: The hand occupies a separate square. The attack comes from that square and would force the creature being attacked to pay some attention to it. If the wizard is also adjacent to the target and sustaining the action, I believe that he/she can still defend themselves and not receive an attack of opportunity because they left themselves open for attack.
I'd rule that since they are sustaining and not casting a ranged/area attack, they would not be a target of OA.
