I'm not finding it with a bit of searching. If you saw it on Khan Academy, it's likely an unreleased game that LSAC provided to them. Otherwise, it might be written by a prep company and unofficial.
ALL questions on Khan are official LSAT questions created by LSAC. They do include questions from PTs that haven't been released, so you won't be able to find them anywhere. No questions on Khan are fake/unofficial.
