Uhh....I highly doubt he knows every jutsu in Konoha. That was just probably an exaggeration. That's literally impossible for anyone. Also, it's HIIGHLY unlikely that Hiruzen knows Bringer of Darkness, FTG, Spirit Transformation, Shadow Paralysis, Mind Transfer, Super-Multi Size, etc. In fact, some of these are only used by specific clans. Hiruzen might know only most nature transformation jutsu.
