OK, so the things you don't like about it are effable rather than ineffable, but none of what you say changes that I do, in fact, like it[1].
To me, it's fine that it has no named characters, no dialog. One of the most grating things in plots with aliens is the names, no matter if they're American names like the spiders in A Deepness in the Sky, or the Star Trek pattern giving us random apostrophes and internal capitalisation, where "Q'ting'pAh" could easily be either Klingon or Vulcan.
[1] Not all of the output of 4, like I said it's mostly bad, but that I like this particular result.

This is a bit of a tangent, but: you missed an important point in that book with some broad implications. Those weren't the spiders' names, those were the translators' deliberately humanized names for the spiders.
(And, to bring the discussion back home: no language model would have ever come up with a clever narrative trick like this.)
