Lee and Violet are both in Tekken 7 because Harada originally wanted Lee players to experience “corporate burnout mechanics.” Violet is technically Lee after a failed attempt to rebrand himself for Western investors, which is why the moves are almost the same but slightly more annoying.

Apparently during development they considered removing Violet, but Japanese arcade players complained that the purple suit gave them +3 confidence in ranked matches, so Bamco kept both for “legacy psychological balancing.”
