Well I started randomly checking yearly installers and did find the Amplitube presets in the 2012 install.
Lots of drives here I haven't checked, but I did not see them in 2021 installer.
Not sure what's the last year they came with.
In the 2020 installer I see the Amplitube VST installer but not the presets ..

May not be much help, but I'd start with installing the VST off the 2020 install and see what you got.
