Is there such thing as a litteral tanuki kimono? Also, I'm going to Japan soon and my mom keeps telling me we can buy a yukata easily in Japan for the festival. Is that true or would they be sold out or something?
Tanuki are kinda rare as a motif and mainly found on wintery items. Folktales are a traditional winter pattern, and those with tanuki often hint at Kachikachi Yama (where a rabbit tricks a malicious tanuki), or Bunbuku Chagama (where a tanuki changes into a tea kettle).
In modern kimono fashion, you sometimes see naturalistic tanuki on some items but they are few and highly coveted :S
On the other hand, modern brands sometimes have them on fun (but a bit pricey) novelty items (hanhaba obi for ex), especially with other yôkai during summertime (monsters and ghosts are linked with summer traditions of "fear", see hyakumonogatari and hyakkiyagyô). Gofukuya is one of those brands.
Outside Japan, I can recommend you 3Magpies and their modern kimono and obi, some with yôkai. But I don't think they've designed a tanuki only pattern - yet ;)

As for finding a yukata during summertime in Japan, it should not be super hard as it is a staple of summer fun and matsuri season :)
We covered this subject here a while ago with super nice @akaomoide giving adresses. Many kimono shops have closed because of covid so take locations with a bit of salt but advices still hold!
Depending on where you'll be based, try department stores and Tansuya second hand shops. Areas around big temples like Asakusa have many small shops and/or fleas markets - just be careful of "fake" touristy kimono (satin and bath-robe belts are usually a bad sign).
Don't forget shopping before leaving is also an option. Depending on where you leave, you might find a yukata easily online.
