I think odds are high a lot of these posts are by staffers. The posting volume is bananas, even granting that he spends a lot more time personally online and watching cable news et c. than any prior president, I don’t think there’s any way they’re all by him.
I do think a lot of the more hot-take type posts (often in response to stuff he’s watching on tv) are either actually him, or he’s dictating to an aide. These larger policy-type ones that he treats as quasi-executive-orders, I think are likely drafted by one or more of his cabinet-level folks, or others roughly as high up. That’s just my speculation based on reading the “tea leaves”, though.
As for official word, it waffles between “all of it’s him” and “oh not that one though, that racist video repost was a staffer who made a mistake”, so that’s little help in sussing out the truth (but I am rather certain they’re not all directly written and posted by him)
