That's the thing are the NPCs capable of learning new things. Ainz did an experiment for one of the homonculus maids to cook a steak despite not having a cook skill. It came out black everytime she attempted. And remember Enri's goblins, I read on the Gpblin troop pagem that they were unable to cook or identify herbs no matter how hard they tried.
