5Dimes has a prop about this:
At those odds, I'll lay the wood and say MVP is from the winning team.
Obviously if the Cavs win, Lebron is the MVP, so that's an easy bet win that has ~25% equity or whatever anyone wants to assess for the Cavs at this point.
But if GS wins, the voters will try to find a way to give it to Steph or maybe Klay/Iggy/Dray can blow it up in the last 2/3 games and grab it. For Lebron to get MVP, everything has to go perfect, he's gotta continue to post up the mind boggling numbers as well as GS's starters need to chop their numbers and get heavy bench production to dilute their numbers. Steph almost needs to disappear not to win MVP if GS wins. I think Lebron has an outside chance of "stealing" the MVP if anyone ever could in the modern era, but at these odds, I'm betting against it.
