For some reason, this is not the default, but I also can't find it as a customization.
I found this tutorial (https://help.salesforce.com/articleView?id=000319963&type=1&mode=1) on how to add Campaign Name (a workaround that adds it as a formula), but the Campaign Name is not clickable, and I can't do the same for Parent Campaign.
Can anyone provide guidance? Thanks in advance.

This will be interesting... I imagine. So it looks like you are going to need to use a lookup field if you want to view the parent of the campaign in an opportunity list view.
Going to be a bit of a pain in the ass.
What my solution involves-
New lookup on Opportunity to Campaign
Flow to update that field when a Campaign is selected/changed
Flow to populate all the old records which dont have this new lookup populated
Fair bit of work to just show the parent record, when you could just set up the compact layout so when you hover over it, one of the fields is the parent campaign
Cheers
