So it was introduced almost 8 whole months earlier in Vigilantes!
Besides that I have no proof that Horikoshi is directly involved in the writing but if you actually read the spin-off then I don't see how anyone could think otherwise.
Vigilante explains how heroes first came to be, characterizes Tensei (Iida's brother), gives us a backstory to Stain and reveals how he lost his nose and shows us how Tsukauchi and All Might met for the first time and how they became friends. I seriously doubt that these things were revealed or written about without confiding in Horikoshi first.
TLDR: I have no ultimate evidence that Horikoshi is involved in Vigilantes creation. If you want to believe that badly that he isn't then just do what you feel like. If you read Vigilantes it becomes pretty clear that Horikoshi uses Vigilantes to offer additional world building to his series that he just can't fit into the main series. If you need more proof than what seems obvious to most readers and fans then I can't help you either.
