In my headcanon, my Tav is the leader of the group because the other characters would constantly be bickering together without a "third party" taking the decisions amid all the contradictory inputs and strategies on how to move forward. Btw, this is the reason why I will always play as Tav, because if I would play as any other OC and put myself to roleplay as they would, there would be no reason for me to follow anyone or any reason for them to follow me.
It'd be great if there was some sort of group companion dialogue that showed this type of thing. SH and Lae'zel arguing, with Astarion adding snarky unhelpful comments and Gale getting exasperated at the lack of progress being made. Gale, SH, or Lae'zel (depending on who you have the most approval with) then turn to Tav and ask for their opinion...a bit more arguing...ending with a compromise that they'll follow Tav because otherwise the party is deadlocked.

Something like that. It would be a bit more complicated to do this for multiplayer, but eh I'm sure there's a reasonable way that isn't to complicated to implement.
