Fair points, Jiraiya's sensory perception should give him a bit more help in dodging Itachi's sword but I am not too sure how much intel Jiraiya would have about Susanoo. Your thesis seems plausible, but then someone like Orochimaru would surely have to have known about the Susanoo as well (since he was in closer contact with Danzo, and Orochimaru having extensive research about the Uchiha), and he did not fair to well.

Jiraiya's speed is indeed faster than part 1 Kakashi but so was Itachi's, who was able to also speed blitz Sasuke in his final fight. Itachi's movements have also been very difficult for even sharingan wielders to keep up with, which is another thought to keep in consideration.

I still feel Itachi edges out this clash, but it would definitely take a heavy toll on Itachi's body afterwards.
