Izanami is a very particular jutsu with very specific conditions, effects and uses. Itachi only knew that it would work against Kabuto because he recognized himself in him, and wanted to give him another chance. He has no such knowledge or guarantee of Madara, in fact everything we know about madara suggests it simply won't have an effect.

Madara was clan leader. It would be ridiculous if he didn't know everything that was on those secret scrolls of secret Uchiha techniques. He's the earliest known user of Izanagi. It would be dumb if the clan developed a jutsu specifically to counteract it and he as it's leader would be unaware.

Itachi's explanation for Izanami includes that "there's a way out, if you accept who you are". If that's how it works, it wouldn't work on someone perfectly at peace with oneself. Plus that Itachi needed time to set up the jutsu, time that he needs to spend fighting a walking superweapon. He's not gonna win. MS Madara is the lowest iteration he has a chance against, EMS Madara is too strong against him.

Look at the facts in stead of wildly extrapolating Itachi's power, and it simply isn't a contest.
