Consider again
I am curious how many people who replied to this question have kids, or are familiar with what a nine year old is all about. Granted, all kids are different, but a nine year old is going in to 4th grade, that is so little. My daughter is 11, so I am pretty close to this issue. Although I can definitely see that your daughter would be attracted to the art work of the thoth, I would not buy my daughter that deck to start learning the meanings of the cards. If you haven't read anything about Crowley himself, I suggest doing that. I think the best that can be said for him is that he was misguided. If your girl was 16, or even 14, I would say fine, but 9 is sooo little, some of those images are ominous and scary. I realize at this point you have made up your mind, but why not supplement those cards with a Rider Waite style that has pictures on the minors to help her learn? Personally, if my daughter asked me for some cards (she uses my Hanson-Roberts deck when she wants to "pick a card for the day") I would probably buy her the Connelly deck, the Robin Wood or the Mary Hanson-Roberts whimsical deck--I would completely eliminate scary images. She has her whole life to discover the more ominous looking decks, but she is only 9 once. Imagining her playing with friends and pulling out these cards gives me the willies. I guess I would like to see her "use" another deck and have the Crowley for cross-referencing. I am not familiar with the other deck you mentioned, but it seems that learning that deck would deepen your learning as well. Don't get me wrong, I am not saying she'll turn into a Crowley because of the cards, but it's something about the vibe of those cards that doesn't sit well with me for children. I think it may be a complete lack of humanity in any form. Even the Empress doesn't look nice, and the Universe card has a big snake on it! The images are interesting, but warm, sensitive? No...No humor either. I would think twice about it. My friends daughter is 16, and was fascinated with my cards the last time I saw them. I was going to send her the Radiant Waite deck.
