An upvote from me, it's a reasonable question.
For your "search for bespoke and unique sounds", that sounds like a service Waves runs, called Illugen. It isn't built in to a tracker, but you can use it to generate the samples that you import into the tracker. Honestly I've never used it, I have too many samples anyway, but here it is: https://www.waves.com/illugen
But you also don't have to go down the generative / diffusion path. You can ask your AI to make a tool to generate various sample files for you mathematically. A good frontier model will happily make a program that will create some hihat and cymbal sounds out of white noise, a kick drum out of distorted sine waves. It will create some simple synth sounds from square waves. If you go deep enough, it will happily go down the rabbit hole with you into additive synthesis while nerding out about the Synclavier. Or it will do synthesis through frequency modulation while chatting about the Yamaha DX7 and don't do that because FM is like modular you'll never find a way out of that hole has anyone seen eno lately.
If you kept reading this far, there's plenty of Claudes already doing their own very simple synthesis & music writing, in videos like these below (two I found today). The models are capable of much much more if you give them time to build a toolset, and aren't just asking them to one shot an entire video about their existence using only a copy of ffmpeg:
