で particle after て form


So i was reading, and suddenly came across this sentence:

俺の力使って **で** 悪魔を殺すとよぉ、すっげえ痛そうなんだわ。

Can someone explain, or provide a website that is explaining this? I wasnt
able to find anything talking about this function.




Is it from the 4th episode of チェンソーマン? I initially thought this should be a
typo, but since this is a popular manga and [the official site has not fixed
this](https://shonenjumpplus.com/episode/10834108156724300654), I have to
conclude this is not a typo.

If it's not a typo, this で should be a particle to mark a condition. That is,
the te-form (俺の力使って) is treated like a noun phrase or a "quote", and is marked
with で.

This 使ってで is not incomprehensible because a te-form can be followed by でも,
ですら, etc., (e.g., 何としてでも成功させる), but I think this 使ってで is at least nonstandard.

(I also thought this could be a dialectal version of 使ってて, but he is not a
dialectal speaker.)
