So I was practising Cala Maria for an IL run when out of nowhere I DIDN'T get frozen in the last section. It seems if you stick close enough to her head you just avoid the attack. I'm gonna test this more but if this is true this'd make her way less of a pain in the ass in full runs.

Video here (it should link to the right moment but if not, go to 1.07):

My guess is that the leftmost part of the attack is what freezes you, and the right hand part doesn't clip you at all.
