I think that there have been such instances - (I can only speculate, but I think that) the judge can rule a mistrial, or it can be heard on appeal.

Ah google to the rescue:

> In the U.S., a jury’s factual findings can only be challenged post-trial if an appellate court or trial judge determines that no reasonable jury could have reached that verdict based on the evidence.

And

Civil Cases - (Judgment as a Matter of Law / JNOV): Governed by Rule 50 of the Federal Rules of Civil Procedure, a judge can overturn a jury’s factual finding if the evidence is legally insufficient to support it.

Criminal Cases - (Insufficiency of the Evidence): Under the Fifth Amendment's Double Jeopardy clause, an acquittal cannot be appealed or overturned. However, after a guilty verdict, a defendant can file a motion challenging the evidence, asserting that the facts do not support the conviction
