> for some reason I think the us govt or anyone else will have a harder time getting to my data

US companies are required by law to hand over your data if given a warrant by USG. They don't need a warrant if they have a subpoena for less invasive data, or a FISA request. They can also ask without any justification, and see if the company will cough it up anyway (they often do). Any AI company with government contracts will want to give up data quicker so as not to threaten deals worth hundreds of millions.
