Itachi's best shot's is hoping that Tsukuyomi would work on Nagato through Pein, but for that to be likely to happen, Itachi has to find out Pain's secret. Beyond that he would have to rely on Amaterasu and instantly burn a couple bodies to nothingness with Amaterasu, just like he instantly burned a fire resistant toad's throat to nothingness.

With that, Itachi could put up a decent fight against Pein.
