If the National Archive can choose not to process illegal or unconstitutional slates of electors then so too can Pence.
I read it correctly.
"If the National Archive can choose not to process illegal or unconstitutional slates of electors then so too can Pence."
No. The Archives has no responsibility to forward random slates of electors that are sent to it. They follow the rules, and that's not how it works. Pence also has to follow the rules. He has no discretion.
