Privacy pass exists, but is limited to 1,500 tokens per month (3, batches of 500). Furthermore, they do not allow disabling safe search or customizing the results in any way (including your block lists) when using it.
Also, since they are the token signer, make sure you use a different IP to get tokens signed / when logged in, otherwise the traffic for the "private" searches is trivially reversible.

So... Kinda useless right now?
