Yes, ghostery is showing that it is blocking segment. I am not 100% sure it is from webflow as I also have a chat running on the page but I think it is webflow.
Webflow does not provide a chat service. Webflow sites can only include other third party scripts (other than jQuery) that you load intentionally on the site.
If you use additional fonts from Google or another service Webflow would load those scripts necessary. Same for Google Analytics, Facebook pixel, etc… that are available in the site settings.
Check your custom code areas to determine what you are loading or inspect the page source.
