Hey there! I’ve been in your shoes before. Have you tried "VPNBook"? It’s not exactly a web proxy for school google sites, but it’s a free VPN that can bypass most school blocks. It’s a bit slower than paid options, but it gets the job done.
Also, if you’re worried about sketchy proxies, this one’s pretty reliable. Just make sure to clear your browser cache after using it to avoid detection.
