"Thiel owns Vance" is obviously shorthand, but is there evidence that Vance is actually under Thiel's control or do they just agree on stuff? I think proving corruption would probably require that Thiel personally/materially benefit from actions that Vance takes in office, not just that he funded Vance's campaign because he agrees with Vance's politics.
Edit: I think there's a much stronger case for some kind of corruption charge against Trump, since he's been using the office to enrich himself.[1]

That should be sufficient. We need to start the process of a constitutional amendment to overturn Citizens United and we need to do as much as we can to enforce existing laws against dark money and enact as much as we can while Citizens United is in effect.
If anything they seem to be friends, with Curtis Yarvin as well, and believes that democracy has run its course. It doesn't really matter if he's just bought by money or if he has bought into the same ideas. Thiel maneuvered Vance into this position using his money and power, and their plans extend far beyond Trump's lifetime.
