However, suppose the district attorney, after looking at the evidence in the OJ Simpson case, had said, “He might have committed the crimes, but we don’t have enough evidence to convict,” and then the family, using the same evidence, had sued OJ Simpson in tort? Obviously the terms and procedures are different in French law, but couldn’t a person be sued in tort for what might be a crime, but can’t be proven to be a crime?

Upon rereading, I suspect I misunderstood your question : you’re asking what would happen if the attorney choose not to proecute, hence if there were no trial at all (actually, in France, the prosecutor doesn’t have a say in the matter, but that’s another issue).
Honestly I’m not 100% certain, but still quite sure that in a criminal case, lacking a conviction, you couldn’t sue the alleged criminal. You’re still acusing him of having commited the crime, and only a criminal court can rule on such an accusation. Note that in France (I think it’s quite different in the USA) a criminal case is handled in a very different way than another trial : for instance there’s no jury in a civil case (actually, not even for a minor crime, like, say, theft or assault), the procedure is entirely different (the enquiry is led by a specialized judge acting on behalf of both the prosecution and the defence instead of a prosecutor), etc…
More or less, the “different standart of evidence” existing in the USA doesn’t exist in France, and is replaced by a completely different procedure to assess guilt for serious crimes. Still, a ruling by a criminal court or a decision by a “juge d’instruction” or an “accusation court” like not enough evidences for a trial or an “acquited” (not “not guilty”) verdict has to be accepted as an established fact by all other courts, and (once again, AFAIK) no regular court can rule on such a matter. If, for whatever reason, a “cour d’assises” didn’t convict the accused, then he is to be considered innocent, period.
