No --
the House of Representatives -- with each state's delegation getting one vote, which favors Trump,
if no one has 270 electoral votes. Unless there is massive faithless electors (highly unlikely), either Biden or Trump will be elected President by the electoral college, getting 270 or more electoral votes.
State legislatures
can't change the
method of selection of electors
after the election. Each state legislature
has already made a decision, before the election, enshrining into state law a decree
that their state's electoral votes will be awarded by popular vote.
And, with individual state vote totals where they are at today (11/17/20), the electors will elect Joe Biden President on December 14, 2020, at each state's capitol, plus the District of Columbia, with 306 electoral votes, assuming no faithless electors.
Any change in state vote totals changing who won each state's electors seems highly unlikely.
In fact, as of the time of the writing of this post, Trump's campaign appears too cheap to pay the close to $8 million cost of a recount in Wisconsin. I'm sure they would come up with the cash if they thought the recount would change the result.
