About いたす
いたす, or 致す as it is often written, is a humble speech う-Verb, which refers to the actions of the speaker (or people within the speakers inner circle, like their company). Similarly to お〜する, いたす means 'to do'.
In the case of する verbs themselves, simply replace する with いたす. For other verbs, add いたす to the ます stem of the verb, while attaching お, or ご to the beginning (depending on whether it is a word of Japanese or Chinese origin).
Caution
Words that include the kanji 拝 'to worship', or 'to revere', do not usually require お, ご, or いたす. This is due to the word itself being 'respectful'.
Fun Fact
いたす is considered to be slightly more humble than お〜する, which means that it will be heard more frequently in advertisements, or being used by company employees.

The example sentence leading to this explanation is:
Kenjougo, Permissiveよろしいですか。(拝借する).
The correct response is: 拝借してもよろしいですかI’m confused as to how the sentence and the explanation are related.

This part greatly confused me because the 募集する example has no お in there!

Yep, this lesson is still a huge pile of confusion, taken at face value. I do think there is some discussion above that helps (specifically comment#39), but I’ve forgotten that nuance multiple times already. And when I get a question wrong in a review (because my memory is not perfect), I don’t come to this thread and read all 50 comments. I go to the lesson, and the lesson still does not explain this, so I get puzzled again.
I tried asking an LLM why
