It's an interesting argument, treating the AI more like a commissioned artist than like a technical tool. But in the end, this seems like the opinion of one mostly irrelevant government office? Copyright protection is automatic in the US since 45 years now, you don't need the involvement of the copyright office at all. For establishing that you created the work, a letter from the copyright office refusing you is as good as a letter accepting your work, and in most cases it's redundant anyways. The only relevant opinion is that of the court where you sue someone else for copyright infringement.
