Use the cookies.txt add-on with Firefox and try using it with the --cookies flag. I tried grabbing cookies from Chrome and for some reason, it worked with Firefox but not with Chrome. Here's an example:

youtube-dl --cookies "cookies.txt" https://www.linkedin.com/learning/python-essential-training-2/hello-world

For more complete info, check out this comment. martin54 explains how to use cookies and also how to use a header in case you're trying to use Linkedin Learning with single sign-on (like I was).
