No. Most of those lawsuits were thrown out without rulings. Generally, not enough process was given to investigate these allegations, which is why half the country supported Trump on Jan 6 until things got violent and moderates got cold feet.
Have you read any of the legal briefs? I read several of the prominent ones, and they all followed the same pattern of leading in with a bunch of easy facts but then jumping to completely unsupported conclusions (that were then used as political sound bites). The cases were summarily dismissed because they had no logical merit.
