Itachi has been shown to kill when he has to, but he generally avoids doing so since he is a pacifist.

Naruto also has Asura's chakra within him and that does jack all in terms of protecting himself from Itachi's genjutsu.

Most of Itachi's abilities are well known but Orochimaru (biggest source of intel in the series) did not know of Itachi's Susanoo and the weapons that it possessed. Itachi only had to fight at what Kabuto thought was full power and he was able to hold back the rest of his abilities in order to help Killer Bee and Naruto.

Do you honestly think he would have became as feared as he was if all anyone had to do was genjutsu: kai in order to stop him? Tsukuyomi wouldn't even give Hashirama enough time to use the technique even if he wanted to and the experiences that Hashirama has experianced won't protect himself from Itachi's genjutsu. Everything that Kakashi had to deal with (mother died while young, Father comitted suicide, Both team mates died in front of him, teacher died, the hokage recently died after the village was nearly destroyed, enduring the 3rd shinobi war) and Kakashi only lasted 1 second in the Tsukuyomi, Hashirama would not last very long before being in a similar condition to Kakashi.

As I have stated earlier, Hashirama would not be able to tell that Itachi is a genjutsu specialist until he is caught in a genjutsu and experiencing drunken dreams for the rest of eternity. Hashirama and Madara's battles relied on ninjutsu and destructive power, but that is not what this fight is about since it is Hashirama VS Itachi.
