The app does not affect keyboard illumination, but you can change this setting in System Preferences/Keyboard:

Alternatively it might be that Apple API controlling the display brightness in Monterey and used by the app is not fully compatible with the 2011 Macbook model as it is not officially supported by Monterey and this causes some strange issues (like changing brightness of the keyboard instead somehow?).
