You can't trust code you don't understand, if you do that don't call it trust, call it faith. Your query has to get decrypted somewhere or else the server wouldn't be able to proxy the request to Google unless it is E2E encrypted but then it is no different than just using a VPN or a socks5 proxy. If that's the case better just use Tor or a VPN and have privacy everywhere instead of just on your search page.
