There is another potential way for Itachi to win other than Tsukuyomi:

1. Create Kage Bunshin

2. Have the real Itachi constantly put Madara under consecutive sharingan genjutsus.

3.Have Itachi's Kage Bunshin cut off Madara's head, while he's incapacitated from genjutsu

Bye, bye Madara. Basically, since it takes time to see through genjutsu, Itachi would just layer another genjutsu on before Madara saw through the first one and keep doing that (leaving Madara incapacitated) until his clone killed Madara.
