It's largely between the agent and the passenger. If they're already onboard, it's between the flight attendant and the passenger.
Just to cut to the chase, if it's a full flight, it's the passenger's responsibility to trade for another seat (if it's not an exit row seat). A flight attendant interjecting to resolve a situation like this is only a courtesy.
