It's not a stretch to say that bots have gotten involved in basically all of the content FFXIV has to offer at this point.

As the previous poster mentioned, while they can't fully automate high-end content like savage/ultimate, they are able to trivialize rotations and resolve certain mechanics; particularly untelegraphed AoEs.

Everything else is free game for them, though, as the few things that are too complicated for them to handle properly either don't punish them for death and/or can be resolved by just having them follow a random DPS player in their party and count on them for safety.
