They sort of went out of their way in the state trial to mock the idea that Kyle was a state actor. Secondly, are we thinking Rosebaum, Huber, and Grosskreutz's criminal histories and documented violent tendencies will be excludable from a civil case the way they were excluded from the criminal one?
Conversely, I don't expect Rittenhouse to be winning in any big defamation sums, either. People like to point to Sandman, but nobody knows what Sandman actually got. You can sue for a trillion dollars if you want. The settlement isn't calculated as some fraction of what you're seeking. It's the product of a negotiation.
"I have here a 1978 Chevy Nova for sale. The asking price is $10,000,000."
"I'll give you 5."
"$5 Million?"
"No, 5 dollars."

If I were Rittenhouse, I wouldn't be looking for a payday, rather getting some key players to desist and to retract.
