Who wouldn't exists if someone else didn't invent something else, which wouldn't exists...

We're all standing on the shoulders of giants here, I don't think one party is more responsible than someone else, unless you're specifically involved with the specific technology, then you can attribute it to them.

So yes, Google's researchers might have invented the Transformer, but OpenAI researchers invented GPT. Does it matter we credit "LLMs" more to one than the other? I don't think so, especially in this context it's highly irrelevant. Google didn't have the "LLM lead" before LLMs even existed...
