Mama Li seems almost as deranged as Sheila (never mind how she got her son out of the hospital - almost as absurd as how Justin Barber got an unconscious Thomas Forrester out of a very busy Forrester Industries building and into the basement of the Spencer Building without anyone noticing).
Maybe she’s hoping when Finn comes out of the coma that he’ll be like Steffy and not remember his marriage. Li saw that hug between Steffy and Liam and assumes they’re back on track to their umpteenth reunion, so she would prefer to get her son away from Steffy.
This is a good story line for B&B.
You are correct, Li is just as crazy as Sheila.
