Unused Java that I am using?

Like many on here, I am trying to help my abysmal page speed one thing at a time. Currently, the biggest component of this is “Unused JavaScript” which must be reduced. See below.

The thing I question is the scripts themselves are being used. allInOneReviews.js is a script pulling reviews from Google, FB, etc. and is actively used on the page. I’m not sure what Webflow.21c11d37d.js is, but the next two are from Vimeocdn.com which is playing my video background (which I also need to reduce the size of, I’m working on that). However, those should not be putting such a load on mobile, because I have code to lazy load them and auto-pause on mobile.

Please, if anyone has any info that would be very much appreciated.
