Is there a lesson that explains this use of l/le? I see it a lot, but I don't fully understand when it is needed and when it isn't needed.
L'on is an optional form of on and is used mainly in the literary domain after words ending in a vowel, notably single sylable words such as: qui, que, ou, où, si, et, to aid euphony . It is never used after the word dont nor is it used before a word starting with 'l' to avoid the alliterative sound of two 'l's'
si on loge chez moi... rather than si l'on loge chez moi...
où on l'avait vu rather than où l'on l'avait vu
In speech l'on is often used to avoid the sound of the vulgar homonym con in such phrases as:
Les toiles qu'on peut admirer au musée which may be rendered as Les toiles que l'on peut admirer au musée
Hope this helps,
In this case the "le" is purely phonetic. It is not a personal pronoun.
