Good point on Kabuto, however there is another example. Madara was able to dodge a flurry of attacks from Sasuke when he was revived despite being blind. I also think that statement of Jiraiya only applies to conventional sensory types, Mu was able to avoid Gaara's sand attack coming from the ground despite not looking at the ground.

Sharingan genjutsu can be overcome with multiple allies (not my words, Chiyo's words), which in this case is toads. If Itachi puts Jiraiya under genjutsu the toads will attack him while he is preoccupied by the Genjutsu. Even then Jiraiya has intel on Itachi. Knowing is half the battle to a shinobi.

As stated in other threads, it matters more that Sharingan users are blinded by smoke bombs and such, because the Sharingan is the core of their abilities. The swamp technique that Jiraiya uses literally creates an entire swamp, so no need to see Itachi, he will be caught in the vast scale of the jutsu. Jiraiya would most likely want to keep up with the theme of blinding Itachi, by using a flash bomb, followed up by Summoning: Food cart destroying technique to break through Susanoo.
