I think you give them too much credit.
From my time living in the US, I got the impression that local oligarchs' personal beliefs are largely aligned with Trump (enabling corruption, oligarch capture of governance, avoiding responsibility for their actions).
However, one relatively unique thing that I noticed about US oligarchs is they tend to be very sensitive about PR and don't like to get their hands dirty (in context of their internal worldview).
They align with Trump in terms of goals, but some may not like his style and presentation.
I would even argue that some US oligarchs may even see Trump's approach as a "low probability, high impact" risk in that he may undermine faith in their rule.
