Yes. The closest thing to the Nobel Prize in computing is the Turing Award, which is indeed funded by Google.

Although it is not Google who decides on who wins, and the Award would still be reputationally valuable if there were no money attached to it.

Funding rarely determines process or outcome.

It's a common argument, but unworldly, given that there are huge amounts of largely autonomous institutions that rely on single donors, may it be public or private money.

"Would you trust a Nobel prize in computing funded by Google?"

Would you trust a Nobel Peace Prize funded by an arms merchant?

The Turing Award? Yes. It is considered by Computer Scientists to be the premier award in the field.
