I think you're underestimating Jiraiya. He would be smart enough to stay out of range of Itachi's Susanoo and would quickly figure out the mechanics behind the Yata Mirror. He has a variety of summons he can use to attack from different angles, negating the usefulness of Susanoo and has a sound based genjutsu which Itachi has no counter against.
