It lets us consider the relativity of viewpoints. The point of the original isn’t just how humans might be viewed from the perspective of aliens. It’s that the apparent strangeness of something depends on the viewpoint and on expectations. The present story is not supposed to stand on its own like the original, it’s supposed to be considered in light of the original. In the original, thinking meat appears strange to the aliens because of their viewpoint and expectations. The present story thus points out by analogy that thinking LLMs might seem strange to us merely due to our viewpoint and expectations.
