Lately I've been watching a streamer who has been a prime target for multiple follow bot attacks.

I suspect it is one of their regular viewers, however there is no real premise to report specifically for suspecting someone of actually launching the follow bot attacks.

And there needs to be a section where any potential proof can be uploaded, such as images, videos, and chat logs.

If Twitch wants more extensive reports, then Twitch needs to provide us with the means to do so.
