For clarification. I think Itachi never used Tsukuyomi with its full potential on anyone throughout the entire series. Not Kakashi (Kakashi admits he would have died if Itachi had not gone easy on him) not even Sasuke (Sasuke manages to escape Tsukuyomi, but it is stated later on by Tobi that Sasuke didn't escape Itachi's genjutsu once, he was able to escape because Itachi wanted him to be). Though who possesses Mangekyou Sharingan might resist Tsukuyomi's effects enough to overcome it and won't die.

This is the only thing worth debating here. Unfortunately, we can't debate it all that well, all because the Tsukuyomi hardly got any expansion or explanation, and Itachi was the only one capable of utilizing it, surprisingly enough. But considering it's Madara, who knows the Sharingan better than literally anyone else, I'd say he's capable of breaking it with his own Genjutsu prowess. Even if he can't, Itachi wouldn't dare waste such a powerful Jutsu on such a powerful opponent, since he can only use the Mangekyo Sharingan thrice a day before he needs to rest, so his best bet would be the Susanoo or Amaterasu, both of which are more likely to be effective.

But we know how this fight will inevitably end. Everything Itachi can do, Madara can do better. The best Itachi can do is delay the inevitable.

...... Unless he can use the Izanami while alive.
