i think rather than paying 40-80 quid for a tool and then using it to bend it back in to shape the cheapest option is just to buy a new mech hanger.
as they are meant to brake rather then snap the mech in half but id be surprised if it also had no damage but i guess we will find out when indexing the gears as mine was bent and twisted to the point the thread was unusable so a tool would have been useless anyway.
up side is hardly any chain noise now crisp up and down shifts with the b screw set right with the sag.
down side is it cost £300 as i changed the hole group set to eagle 12spd gx
