There is no way LinkedIn will let you scrape millions without any pauses. Have you tried with randomized pauses? Pauses between each request and using rotating IP's will help you.

how can i get the cookies without selenium, only with request library? i just neet the s.cookies['li_at'] token

@jorge3018 You can just log in using the requests library with your username and password. It is simple enough.
