as said by lion chakra,the reason itachis crow made eye contact was because it was programmed to activate when it sees itachis ms.otherwise eye contact is not required.also i think danzo could use it without uncovering it.

as for defeating kotoamesukami.the exact effectiveness of kotoamesukame is still a bit unclear.like itachi was commanded to protect konoha ,and at the time sasuke was contemplating destroying konoha,but itachi didnt harm him,contradicting the genju.perhaps its not as infallible as we think
