I'm looking into this.

I don't think $LC_MESSAGE applies here.  This is not about (error)
messages.  Checking $LC_ALL is useful though.

There are a few mistakes in there.  How about this:

  let s:lang = ""
  if exists("v:lang")
    let s:lang = v:lang
  elseif strlen($LC_ALL) > 0
    let s:lang = $LC_ALL
  elseif strlen($LANG) > 0
    let s:lang = $LANG
  endif
  if s:lang == "C"
    let s:lang = ""
  endif
