screen and keyboard backlight are controlled by the graphical desktop environment. On my laptops (with GNOME) the keyboard backlight goes off as soon as the screen turns off.
TLP is not aware what happens in the GUI and does not know when, for example, the screen is locked or turned off. TLP also principally does not manage things controlled by the desktop. This avoids conflicts and makes it transparent for the user what controls what.
In your case you have to look into the desktop environment. Maybe a kernel interface to control your hardware is missing.
