Okay so you're absolutely right, it probably SHOULD be "Arisu" but to make sure, I digged through merch, searching for those cards or merchandise that have the name of the Cures in English. From memory, I think they had stuck with Alice despite it being in hiragana but I had to double check! And it turns out they had stuck with Alice despite her name being in hiragana.

I mean you're absolutely right. Katakana is for foreign words, hiragana for native words, but I guess Toei decided to ignore the rules...
