I came across the same issue with Native trainer, when I wanted to use it.

BUT

I found a solution!!!

I used this old ask Ubuntu thread: LINK

Keep in mind: I did this on GTAV installed from the Epic Games Store through Lutris.

Instructions:

Install Script hook and Native trainer as you would do on windows

open the wine configuration of GTAV's wine prefix

go to libraries

In the New overreide for library field select dinput8 from the drop-down menu and clik add

Apply the changes and close the window

Enjoy the trainer!!!

I guess if you install any mod, that uses custom windows system dll (just as Script Hook does with dinput8.dll), you just need to repeat these instructions for that specific dll.
