That's the definition that matters. And as it's impossible to describe in words what it's like to experience qualia, and LLMs are trained on words, they cannot know what it's like. Even if images and sounds are included in their input training data, those are just arrays or sequences of numbers, not the experience of seeing and hearing.
Their training data isn't qualia itself, but neither is your training data.
Qualia are something you get on the inside in response to inputs. I don't see why LLMs can't have them. I'm not saying they do, but I don't think your argument proves that they don't.
