When adding a light from:
Add → Light → Octane Light Library
it:
- loads the light from the Lights datablock
- creates it in the scene
- places it at the 3D cursor
- sets it as active

Install the attached .zip from Preferences → Add-ons

Notes
- Temporary workaround
- Non-invasive (does not override existing operators)
- Not needed once the issue is fixed upstream
