If I understand correctly you want a Google search to return only those results for sites that do not pull content from any other domain and that aren't connected to big business.
How do you determine what benign content should be left without having to manually load each site to see if it works?
I think the closest you're going to get is to load the uMatrix extension to stop cross-site requests, (be prepared to click a lot to get a site to have minimal functionality), and try a different search engine where you can remove results based on certain criteria, eg. MillionShort
There's also the Google Hit Hider
userscript so you can remove Google, (and other recognised engines), search results from whole domains.
