One time come over the top with total garbage (NOT a potentially dominated hand like KT or QJ). If you get called, check fold, if she folds good. Either way: show the hand ! This will let an aggressive player know that they risk being played back at, and that you are not an automatic blind atm. If you play a card contingent style where you wait for a good hand to re-aggress, then a good LAG will just get out of your way, putting it down to the cost of doing business. Then right back to stealing again, while you wait for another hand. You need to slow them down, or at least point out to them that there are easier targets at which to direct their attack.
Also, this becomes a lot less of a big deal if you yourself are stealing from other people. "Steal and be stolen from": just make sure you are doing more of the former than the latter.
