Ms Lewis was asked about antisemitic comments the killer had made, and also references to the 2017 London Bridge terror attack, but said these were not referred to Prevent.
She said: "I didn't think they would do anything about it."
She also said an incident when the teenager was found with a knife on a bus was not reported as it was not on school property.
Ms Lewis was earlier asked about why a search for a "nunchaku", a traditional East Asian martial arts weapon, was not recognised in a safeguarding technology tool the school had used.
She said it should have been, and should "possibly" have been mentioned in a Prevent referral too.
