The vast majority of the "LLM have no qualia" discourse is mostly using it as a starting point to arguing that LLMs will never be able to X, however. This is a category error that makes no sense on its own--qualia or lack thereof doesn't affect capabilities, p-zombies etc--but that connection does make sense if the speaker is bringing in a hidden assumption of a dualistic human soul that imbues both qualia and additional capabilities to raw matter.
