Your mistake is to think that Itachi is not a fodder compared to Mingo. That's all, you expecting fight where it's yc1Mingo carbstomping pre TS Luffy lvl guy with some hax.
1. Amaterasu is easy to counter with string block, especially when amaterasu never burned anyone noteworthy even in Naruto lol and is way too slow to land on Mingo based on speed scaling between OP and Naruto verse.
2. Haki can counter illusions which i already said. There's a DF powers based on illusions like Mont d'or book illusions.
3.You are underestimated range difference between them aswell.
Itachi needs to get close and make eye contact while Mingo can cut him from miles away.
