Itachi couldn't counter Tayuya's chains of fantasia without Sasuke's help, and since toad chant is much stronger than that, it stands to reason that Itachi is helpless if he is caught in the toad genjutsu. In part 1, Ebisu said to Jiraiya that Orochimaru was still a threat and that only he(the only Konoha shinobi) was strong enough to take him on at that time.

Now I know this is Naruto and not the real world but, since there is gravity and other physics concepts present, the speed of sound in air is assumed to also be this in Naruto.

Therefore, if the genjutsu is completed there is no escape for Itachi. The toads were not exhausted after the genjutsu, but I do agree that they will not be able to spam this genjutsu. Since Itachi will most likely be in his Susanoo when this genjutsu is cast and his Susanoo is not as mobile as he is plus he is susceptible to genjutsu in his Susanoo it's Jiraiya's win, no need to spam.

P.S. the toads use senjutsu, which implies that they each have extreme reserves of chakra in the first place, meaning at the very least, Itachi will run out of chakra before they do.
