Kakashi never worked with Itachi when Itachi had the Mangekyo. Itachi was surprised Kakashi knew anything about the mechanics of the Mangekyo later.

I mean, even Naruto saw Amaterasu coming when he wasn't even in Sage Mode.

Part 1 Kakashi isn't on Jiraiya's level, and NTCM Naruto can't sense anything except negative emotions, and both were able to sense MS techs coming. So I'm pretty sure Jiraiya can too.
