taako absolutely has spells to contain this thing on the short-term, if people could get it into a container in that time. specifically he has a spell called Resilient Sphere that traps something in an unbreakable bubble for a minute- so if it could be moved in said minute into a more permanent structure, that might work. He also has a good shot at killing one as long as they're not bumrushing him seeing as that went so well for Harlan lmaoooo
