>>43771242Aside from the official tutorials on the live2d site, there's Brian Tsui's video course with tutorials on the different parts to rig and the live2d discord with miscellaneous tips on different things and an overview of the rigging course. You can also just look for youtube videos on whatever specific part you're working when you get stuck. I find the free version of live2d cubism to be extremely limiting in what you can rig but for the absolute bare minimum it might be enough. I'm practicing rigging on whatever free models I can find and it's really tough, webm related. I see why riggers charge so much when it took me at least 5 hours to rig eyes alone to a presentable state.
I found this video gives the best overview on every part of an average model and a decent explanation on basic rigging for each.
