I guess you didn't read the Manga, cause you would know it's literally stated in that chapter by both Zetsu and Itachi, that specific Genjutsu of Itachi reaching and grabbing Sasuke's eye, was Tsukuyomi. Read chapter 388. I also see you neglected the 2nd Databook's entry as well, which flat out states "Concurrently, the only ones who can defeat Tsukuyomi are Sharingan possessors… And even then, exclusively the elite shinobi who have reached particularly high degrees of skillfulness". Then it goes on to say only those with Uchiha Blood.

So your going off based off what Zetsu and Itachi said? How would Zetsu know whether or not it was Tsukuyomi? Also Tsukuyomi last for an instant. We can tell that the illusion Itachi put on Sasuke didn't last an instant, because Zetsu reacted mid-illusion. If it was an instant it would have ended before Zetsu reacted.
