Kakarot96: Leave a companion a bit far away from the seller and, before closing conversation, transfer the items robbed to that companion. Let the seller inspect your pockets while you yell: "But i have nothing to hide!" Seller will be satisfied and will leave you alone, forgetting what happened and returning to the initial non hostile mode.
PS: only yell to the seller if you are playing with a friend and he or she hears you. Otherwise, your family/neighbours will think you are crazy.

This is great advice, I never even knew you could switch characters while in a convo. I always just ran like hell after and it didn't always work ;)
If you were able to do this (convo switch) in the first game as well (EE), I didn't know that either. Good god that would have made the constantly walking around vendors so much easier - and many less reloads.
