Itachi was able to cover the mountain area with ameterasu and use it several times during the battle against Sasuke. Itachi used Susanoo for enough time to beat Orochimaru and he could of also taken out Sasuke, while Itachi shouldn't have had enough chakra to use any jutsu AT ALL! Techniques like: Tsukuyomi, fire ball jutsu, crow clones, etc were also used in the battle.

Jiraiya's sage mode makes him faster and he is able to predict his opponent's moves, but neither of his feats outclass Sasuke's speed and perception (Sasuke couldn't avoid Itachi's Taijutsu and Ameterasu).

Jiraiya requires a field which has a lot of terrain between himself and Itachi in order to win this fight. Terrain between himself and Itachi could be used to stall Itachi, while he uses his genjutsu (provided it works) and obstacles in the way could be used take ameterasu. Itachi has a few techniques to combat this strategy however (Yasaka matagama, ameterasu and long range genjutsu), so even that is not a completely solid strategy.
