Vice president doesn’t have power to ‘change the outcome’ of elections
That is dead wrong, and doesn't make any sense.
Can you point to anything in either the United States Constitution or Federal Election Commission law, which grants the Vice President the unilateral discretionary authority to decline to count electoral college votes?
No, you can't ... because it's not there. Hawaii, in the 1960 Presidential Election was close enough to mandate a recount ... Michigan in 2020 was not. Your examples are not analogous with each other. Michigan in 2020 was never going to be under recount. Biden won the state by 154,000 votes!
