Itachi only said that in reference to Sasuke himself, because he wanted Sasuke to be the one to kill him whether he had to hold back for Sasuke to do it or not when the time came. Sasuke fully believed that until he learned the truth from Obito etc. Tsukuyomi cannot be broken by a normal Sharingan, only a powerful MS user who is an Uchiha and even then that is speculation on its own. Itachi killed a 3 tomoe Sharingan user with Tsukuyomi in the novel. He put Kakashi out for weeks with it, and he put Sasuke into a coma with it and he wasn't trying to kill or permanently disable Sasuke either.
