Use something like Searx [1], either self-hosted or hosted by someone or some organisation you trust. You can still get Google search results if you feel the need, either by explicitly asking for them (!go for search, !goi for images, !gon for news, !gos for scholar, !gov for video) or by enabling the Google engines in your config. In the latter case you get Google results mixed up with the other enabled engines. The results are presented as normal links without redirection through the originating search engine.
Searx can be extended so it would be possible to create a plugin which rewrites AMP links into non-AMP equivalents, where available. It can already do things like Open Access DOI rewrite (Avoid paywalls by redirecting to open-access versions of publications when available) so the ground work has been done. I'm currently working on improving (and fixing, where necessary) the image search engines and will probably start on such a plugin if nobody else beats me to it.
