Tell your boss what everyone knows: This team sucks and it's the boss's fault for building a shitty team. This is a classic pattern, where you have a team in full dysfunction with a lead who is not empowered and a boss who is not aware.
It is not acceptable to divide the leadership that way. You either need the ability to hire/fire and fix that team, or you have to quit.
