You apply pressure on companies taking investment from the Saudis collectively.
If you can’t support Uber because of an atmosphere of sexually harassment, how can you support them when their investment dollars are coming from a country that subjugates women? That creates an indentured servant class from imported labor? That sort of argument. It’s blood money, and that’s the narrative you use (if one was so inclined).

That's just rephrasing it... how do you apply pressure? Everyone needs oil, many don't care about these issues, so how do we make them toe a line? What pressure do we exert? How much political capital do we burn without a hope of return?
At the end of the day though, you say "blood money" as though both sides aren't drenched in it. Moreover, whoever the Saudis are killing, it's with our weapons systems. They're newcomers to a game that the US has been playing for centuries, and Europe much longer. They're something between our rogue asset in the region, and our abusive soon-to-be-ex-spouse. Everyone sees it coming, especially the Saudis who are going so far as to clean house and contemplate an Aramco IPO to avoid being reclaimed by the desert.
Diplomacy is the art of saying “good dog” until you make it to the rock. We’re not to the rock yet.
I’d agree with your sentiment that they’re too much of an ally for anything meaningful to be done about their investments, but the winds shift quickly.

Failing that, you’ll have to resort to politics.
