It's actually fairly straightforward. People clicked on him and then the person mentioned in the meta description. I've taken screenshots of the meta description then then linkedinpage here:
It's not HIS info that is coming up - it's the "People Also Viewed."
The quickest way to get rid of this is to go to his profile, click a bunch of unrelated people to 68 Degrees and get these people off his sidebar, then when Google reindexes the page they may see different info.
Also, build up your own SEO & presence as Moosa suggested. Twitter, FB, real link building to your own site. You only have 2 links on Ahrefs. When you have 200, he'll most likely never appear for this search as all your own pages will. You just need better SEO on your own site but in the meantime you can remove this from LinkedIn just by changing who has been clicked yourself.
