Good luck actually unsubscribing from LinkedIn emails. The dark pattern they employ (or at least used to employ, for many many years) is to just periodically add new "categories" of email to send you, that you haven't yet unsubscribed from. Back in ~2015, out of frustration I changed my LinkedIn email to a throwaway

I unsubscribed from LinkedIn emails but they still send me emails of people I should connect with.

Now debating whether I should delete it altogether.

Nothing that inbox rules can’t fix. I just pass all LinkedIn mails to dev/null on arrival.

While I also dislike LinkedIn a lot, I unsubscribed once in the past and I haven't received a single email like that in years.

This would be illegal in the EU + UK, and certainly doesn't work like that in the UK. Potentially LinkedIn only made that change based on jurisdiction so maybe you two live in different places?
