Cheating tools have pushed Google back to in-person interviews, where somebody watches you code and you cannot cheat your way through it.

I think Google has pretty much gone to on-sites at this point, back to the traditional whiteboard format. And they'll let you code on a laptop if you want to, as well, but it's going to be in person. Somebody's going to be watching you code, and you're probably not going to be able to cheat your way through that.
