Itachi is invincible in 1v1 battle based on the facts. He is only invincible when he is holding up the yatamirror which requires him to hold up susanoo which takes a lot of chakra. In battles against multiple people, he wont have the stamina at all to hold it up forever. For example I theorized for a while that if the akatsuki bum rushed him, he would be able to take out hidan, deidara, kakazu and possibly kisame before he is unable to to hold up susanoo anymore, at which point he is screwed despite his high skil. He won't be able to deal with pain and obito at that point.

At ninja war, breaking the genjutsu via pain only works on lower tier illusions. If the illusion is complex enough the environment around you will change too much, naruto had no way of using the pain method. Like I said, naruto was only inexperienced at recognizing illusions. Jiriaya clear ly told him how to break it and breaking them is a feat of strength/chakra. The sharingan doesnt break illusions it helps in recognizing them, you still need the focus and strength to overcome the illusion. Hashirama avoiding eye contact without failure is bs and you know it. His fighting style is extremely head on and direct and he fought an uchiha that rarely uses genjustu to begin with. Avoiding eye contact is not something easy to do when the sharingan hss precognition on where you are staring. Itachi has tsyukyomi so hashriama loses if he makes even brief eye contact.
