Facebook Lite cannot fix the OS. However, because Lite limits background processes and doesn't request excessive permissions (it asks for Storage, Camera, Location, and Microphone, but doesn't demand "Phone" or "SMS" permissions often abused by malware), it is safer than running a bloated, older version of the standard app.
