No.
Republican legislators are from Republican districts. The level of evidence required is far, far below what a court would need.
All they need is doubt. Not even certainty. You have this rather a lot wrong. They have nothing at all to lose by making this choice.

Not every Republican state legislator is from a safe Republican district. Plenty of them have to win over swing voters. I also think you are underestimating the number of Republican voters who would have a problem with their state representatives voting to disregard the outcome of a Presidential election in their state absent compelling evidence.
Legally, they don't need any evidence at all to exercise their power to appoint electors. Politically, they'll probably need conclusive evidence.
