If adobe use any AI tools to help develop photoshop, its all been loaded in. Or if its ever ended up anywhere on the internet, even in private

The first part (re: AI tools) is ostensibly not true. It all depends on the degree to which the data that they "don't train on" gets laundered and anonymized to the point where they are able to justify training on it without it being "yours" any more.

And I don't think that is publicly known at the current time. (If anyone has any tangible info on this, the please let me know...)
