“agency” is an emergent feature.
But, it's not. It's something people attribute to the random series of words that are generated, but no agency exists.
It makes sense to me to accept that if it looks like a duck, and it quacks like a duck, then it is a duck
Or it's a video of a duck, which means it's not a duck. In this case, just because it fools people into thinking there's consciousness / agency doesn't mean there actually is any.
