We've seem them on a hunt with Naruto and Roshi, but we have no idea when Itachi even got the Totsuka Blade. Maybe he got it after sometime after finding out Sasuke had Orochimaru inside of him.

As for Orochimaru being pierced, the way it looked, it was something that he could not react to, but considering he felt he was immortal, he probably wouldn't have dodged it anyway.
