Well there is no data there so it’s been deleted, google is apples default search engine in safari so i’d Imagine that’s why you can’t delete it.
this is not correct.
if you delete the data, it would stop appearing there. that is the normal behavior.
however, in the OP case he has noticed that that that one website's data can not be deleted. its virtually undeletable.
i have one site as well that i delete but it reappears immediately just like the OP.
in my case its not google. its a vietnamese website that i did visit one time.
i also want to know what kind of supercookie is at work here that is preventing it from being able to be deleted.
there is also the case it seems that if the site is being visited to pull in data (such as a weather.com site) then that data is also not deleted as well. but in that case there is probably a widget or other app that has been given permission to pass data such as location tracking permission so it is instantly again appearing.
but thats not the case at all in my vietnamese example above.
however, i found the way to delete it.
here is a copy and paste from

Hi there I am not sure how old this post is but I have the solution. It's very particular about the steps you take, so follow each step. I own an iPhone7 iOS 10
1. Set cookies to allow
2. Make a list of all the websites that won't erase from your website data.
3. Visit each site (on safari) doing the following steps.
4. Once you have safari open with the website that is storing data on your device, leaving the window open (press home screen button)
5. Open: settings>safari>advanced>website data
6. Swipe the current website that is open in safari
7. Delete
8. Click back twice
9. Double click home screen button and close safari first then close your settings window
10. Repeat steps for remaining website data stored on your device
