There's no guarantee Izanami would work on Madara. The latter always believed that all he was doing was right, Madara never had any identity crisis or something. His only mistake was to trust Black Zetsu, while he couldn't realise it since he didn't learn the truth about it to the very end. All the other actions weren't mistaken, at least, he thought that way. And secondly, there's no guarantee that Itachi's treasured tools are so hax they were described to be. We didn't see enough proof in the series that TB can really seal anything or that YM can really block anything. Their actual feats are pretty limited.
