One powerful Tatsumaki on the tea party would probably beaten the whole family except BM herself.
But such a move would have targeted the allies too unless they are hiding inside Bege.
The whole family is made of weaklings and the only powerful figure among them is Linlin.
And Zoro was trash-talking her since FMI saying she has tiny balls and was excited to fight an Emperor since PH.
Just like Nami literally said, if they wanted to fight her, they would have brought Zoro.
High IQ responses - Zoro fights all but the one manga said.
