Screenshot included for Karje, the dye merchant, however several others are also aggressive, including Iana the healer and Syn the smith. Guessing they aren't tagged as being part of the faction or something.
Additionally Urkart on the hill northeast of the Iarnwood encampment and Asutri at the Modernagrav encampment also remain aggressive. Unsure if this is intentional as they seem to have unique drops.
