I cannot comment on LLMs for music generation but, if you are starting from scratch, there are a few methods that I think are interesting.

• Sequencer/Groovebox: Hardware like the Elektron Digitakt and Polyend Play+ use the "piano roll" style generation that you find in most DAWs. How you import and edit samples, then sequence them in the piano roll, varies from one to the other. Fortunately, you can find a lot of video tutorials for most DAWs and hardware based sequencers on YouTube.
• Music Trackers: Whether it is a hardware tracker like the Polyend Tracker or the M8, or a software tracker like Renoise, this type of sample edit and sequencing really lends itself to electronic music. Plenty of tutorials on YouTube.
• Samplers: Here you have hardware like the Roland SP404 MKii, the MPC One, and the Teenage Engineering EP133 KO II and DAWs like Native Instruments Maschine (also requires Maschine hardware). If you have a tablet, check out Koala Sampler. It might be the best $5 you'll spend this year.

In my opinion, trackers are an extremely fast and powerful way to create electronic music. The main complaint people have is the learning curve since almost everything else uses the "piano roll" method. Since you are starting from scratch, that complaint doesn't really apply because no matter what you select, you'll have to learn from zero.
