I think people are missing the threat. The Trump campaign doesn't need to prove anything to a court

50. Before your speculations

get completely out of hand, I suggest that you read through the following links carefully.

Legal Provisions Relevant to the Electoral College Process https://www.archives.gov/electoral-college/provisions

SUMMARY: STATE LAWS REGARDING PRESIDENTIAL ELECTORS https://www.nass.org/sites/default/files/surveys/2017-08/research-state-laws-pres-electors-nov16.pdf

Should any state legislature attempt to certify electors in a way NOT in accordance with its own state laws, then ANY US citizen of legal voting age who is a resident in that state would have legal standing to challenge that decision. Do you REALLY believe that legislators - even GOP legislators - would allow themselves to be open to such a challenge?

As for the US Supreme Court even getting involved, please remember that the US Supreme Court is NOT a court of first-instance except in VERY special cases. Selecting Presidential electors has never been one of them. In Bush v. Gore, the holding was about the counting of votes.

Supreme Court Procedures https://www.uscourts.gov/about-federal-courts/educational-resources/about-educational-outreach/activity-resources/supreme-1

From the link:

...
The Constitution states that the Supreme Court has both original and appellate jurisdiction. Original jurisdiction means that the Supreme Court is the first, and only, Court to hear a case. The Constitution limits original jurisdiction cases to those involving disputes between the states or disputes arising among ambassadors and other high-ranking ministers. Appellate jurisdiction means that the Court has the authority to review the decisions of lower courts. Most of the cases the Supreme Court hears are appeals from lower courts.
...

Please remember that there is NO state where Biden has won in 2020 that has a margin of victory anything like the extremely close margin in FL in 2000 in Bush v. Gore. Please also remember that the GOP has already sent challenges to the US Supreme Court wrt this election and, except for the deadlocked decision on PA absentee ballots which left the state decision in place and its follow-up which compromised by separating some absentee ballots, the Court has sent everything back forthwith.

Here's a recent NPR article that lays many things out. https://www.npr.org/2020/11/07/932214005/will-this-election-be-a-replay-of-bush-v-gore-at-the-supreme-court-not-likely

Like you, I believe that GOPers will try every dirty trick in the book. But those dirty tricks are just that. They are not legal arguments. So please just stay the course.

FWIW: this is my last response to you in this OP. Google is your friend. And yes, I am an attorney, although now I am retired.
