As simple as the title suggests, just some place to find someone, I've recently become obsessed with the hypnosis kink and I would like to try and rp a scenario or even try getting hypnotized by someone through maybe an online VC or something.

You could try on the hypnohentai discord or the darknosis discord servers.
I do think both of them require some form of age verification though, especially if you are looking for stuff other than RP.

There is also r/hypnohookups I think.
