Obito won't be stopped with normal Sharingan genjutsu, Tsukuyomi and Izanami can and will affect him though, with him breaking out of Tsukuyomi and him losing to Izanami. Itachi is so fast that literally all he needs is a split second to kill Obito, and Izanami or Tsukuyomi will afford that to him. Obito knows what Itachi can do and he knows he isn't winning that fight.
