I'm an impatient reader and I skip parts I think don't matter to the story, like what exactly happens in a fight, or descriptions of clothing. I didn't notice any of the errors you mentioned.

For example, on the «“You are in good hands, dwarf,” said Gimli» part, I pattern-matched to [boisterous protagonist remark] when I saw the opening quote, and skipped until after the dot.

My point is: to a reader like me, this "filler" (that's not the right word, but you get what I mean) could be machine-generated and I would barely notice it. I guess an author could concentrate on writing the "important parts" and let the machine "fill up the gaps".

That filler is in there for other audience members. I think of clothing descriptions as filler too, but I remember Brandon Sanderson mentioning how female draft readers for Mistborn kept objecting to him that he wasn't going into enough detail about what the protagonist was wearing.

You may not notice that text you didn't want to read anyway is just random self-contradicting gibberish, but someone wanted to read that part of it, and they will notice.
