There's nothing linking together random NPCs to portraits in escort quests (it just uses one of the player heads). For conversations, the square portraits are usually a good match but there are some issues around this in classic which we inherit. I believe Nystul is working through these to improve conversation portrait matching as he has time.
it is described how we can change portraits so they match. create a list according to the instructions and we can patch it
