You don’t need to control the spell or ability that creates the tokens, but the tokens do need to be created under your control.

If another effect modifies which or how many tokens you create, you choose the order to apply those effects. For example, if you control this creature and Anointed Procession (“If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.”), each time you create tokens, you can choose to apply Anointed Procession’s effect to double those tokens first, then apply this creature’s effect to create an additional Thopter token. Or you can choose to apply this creature’s effect first followed by Anointed Procession’s effect, allowing you to create double the original tokens plus two additional Thopter tokens.

If you copy a permanent spell, that copy becomes a token on the battlefield, but that’s not the same as creating a token. You won’t get an additional Thopter token that way.
