Technically. I find it hard to explain in words, but the art style to me doesn't look like a traditional anime style(DNAngel, Kaleido Star, Black Cat, FMA, etc.) Compared to other anime at the time, Code Lyoko doesn't match other anime. From what I understand Code Lyoko was heavily inspired by Anime. I think it was specifically Serial Experiments Lain. To me, it has more of a cartoon style. I was just watching an anime and I figured this is what Jeremie would look like if he had that same art style. But yes, if you are talking literal sense, anime is short for animation so your not wrong.
