That assumes chibaku tensei goes off in the first place. From what we know, chibaku tensei doesn't affect deva path (probably due to his control over attractive forces), but there is no proof that the other paths wouldn't be affected. Chibaku tensei seemed to be on par on with chou shinra tensei, in terms of chakra required, so its unlikely that he would be willing to shut off his other pains and what not to use it, and even if he could, it's not a move that he uses right away when he uses the 6 paths of pein. I think it would be a move that he would use if Deva path was last standing, and that isn't a gaurantee. Pein would protect the Deva path to the best of his ability though, given that its his strongest path.

As for how itachi deals with the core, there isn't enough evidence... What is the minimum damage required to destroy the core?? Just like there isn't any proof he can destroy it himself there isn't any proof he can't. But logic would dictate that with repeated attacks, he could theoretically destroy it. Also, in theory, based on itachi's mastery of izanami and knowledge of izanagi, he can also theorectically use that if everything else fails, and since this is a hypothetical battle and not a plot related one, he might be willing to risk losing one of his eyes to escape. IF that isn't an option, then sure, Itachi loses to chibkau tensei, in theory.
