I disagree with this change. LLD isn't a word or a pronouncable abbreviation, it's an acronym.

victory, it is about death.  I've seen thousands and thousands of dead bodies.

"Traditionally an ell ell dee [...]" sounds correct to me.

Ah bay tsay day vitamin.

I disagree with the disagreement. LLD gets pronounced as "El El Dee" so its "an", "a El" doesn't flow and requires a stop. Btw it should be L.L.D. I suspect ;)
