There is a much greater chance of Itachi being able to counter/prevent Jiraiya's sound based genjutsu, as Itachi has mastery of genjutsu and this is a prominent factor in if a person can or can not escape a genjutsu.

Jiraiya's genjutsu also requires a lot more prep time than Itachi's genjutsu, taijutsu and ninjutsu which makes it much more difficult for Jiraiya to pull off the genjutsu in the first place. Itachi also has the ability to use crow genjutsu clones in order to deceive Jiraiya into believing his technique had landed, and then launch a counter attack.

Itachi may also be able to reverse the genjutsu back onto Jiraiya, and if this is the case then Jiraiya's win condition would potentially become yet another win condition for Itachi.
