Even if it was, the author is not a random person and is part of the FreeBSD team and I'd rather trust them to write the book than someone else outside of the organization.
So I would expect that they would thoroughly check the book for inaccuracies, errors and issues before releasing it after proof-reading, otherwise it would say a lot about how they use LLMs and not checking over it would hurt their own reputation.
