The file name for the package is kde-services and I cannot find it in our repos. The only place I can find it is in the KDE Store. That can only mean one thing. The only way to get rid of it is Discover.
I don’t know how you received your KDE-Services, but a week or so ago I was having trouble getting Samba to work properly with an external USB drive. I noticed one of the tools available in that package was for Samba, so I installed it with Discover.
It was not what I was looking for. But it did lengthen Dolphin’s right-click menu by a massive amount. An excellent way to make Dolphin extra-complicated for new users.
I removed it with Discover. Nothing went sideways. Then I installed it again. Still, nothing went sideways. So I removed it, knowing that I can always re-install if needed in the future.
