Yeah, L has a bunch of different pronunciations...
I am pretty sure /l/ is [ð] in intervocalic position, and not just word-initally after a vowel (which is "Vl", so that is not strictly word-initally, but I guess this means "#Vl"?).
What I meant by "word-initally after a vowel" is "word-initially only if the preceding word ends in a vowel", like in
la livertà (Scurz. Gram., page 13). The Talossan Pronunciation PDF that Miestră attached above and the Introduction to the 1997 Treisour (
link, page 13) share my interpretation.
talossan.com and Hool say that /l/ > [ð] always occurs between vowels, but Cresti disagrees:
link.
I don't know, it looks to me like /l/ > [ð] / V_V was just a misinterpretation on Hool's part that somehow managed to get into talossan.com unnoticed.
