As usual, Linlin spoils her children as they’re useful, and discards them after they’ve served their purpose. Pragmatism in its most childish form isn't parenting. Katakuri, Pudding, Opera, Zeus, Lola, Chiffon, etc... abandon the family at slightest glimpse of appreciation from someone else. I believe this is connected to Linlin and Katakuri’s overall arc. O-Lin will play a role soon.
