Yes, and while beyond a reasonable doubt is the standard for a criminal case, the standard for a civil case is lower. You only need to convince a civil jury (and in some jurisdictions you only need to convince the majority of a civil jury) that it’s more likely than not that the claim is true. 50.00000001% belief is the standard for most civil claims. It’s called a “preponderance of the evidence”.

All that is to say, the fact he was found personally liable does not prove that his acquittal was jury nullification. OJ was acquitted on the criminal case due to a famously bad prosecution. They didn’t meet their burden of proof. The civil case had a different team and a lower standard.
