KDE does not use lightdm by default, it used sddm. Also no labwc but kwin_wayland. So a purge of packages lightdm and labwc will leave the KDE natives as default. At login screen there should be a selection option for X11 or Wayland session. So no editing of conf files should be needed.Since rpios Bookworm you need to edit /etc/lightdm/lightdm.conf
Comment out any lines referring to LXDE-pi-x or labwc
But I haven't used KDE5 for more than a year, only KDE6 since a year, there might be issues with KDE5 RPiOS also depending if Pi4 or Pi5 and X11 or Wayland.
