AI Turo/Sada represent to me the side of Turo/Sada that had a grasp of reality and wanted the player to stop them from destroying everything with their own unchecked ambition. The kind of ambition that was originally well-meaning but turned into an addiction. It's quite tragic for a Pokemon story...
Thats's the Lead Guitar from the Soundfont "Ultimate Guitar Kit", aka UGK Guitar, with the Revalver MK 3.5/HPSE amp, power metal preset. Its the same setup used for the lead guitar in Hopes and Dreams in undertale.
