My fmtutil.cnf says

...
lualatex luatex language.dat,language.dat.lua lualatex.ini
...

My language.dat has

...
% from hyphen-italian:
italian loadhyph-it.tex
...

while language.dat.lua has

...
-- from hyphen-italian:
  ['italian'] = {
    loader = 'loadhyph-it.tex',
    lefthyphenmin = 2,
    righthyphenmin = 2,
    synonyms = {  },
    patterns = 'hyph-it.pat.txt',
    hyphenation = 'hyph-it.hyp.txt',
  },
...

On TeX Live all known languages are always enabled by default. It's probably sufficient
to uncomment the relevant line in "language.dat" and say 

tlmgr generate language.dat.lua

since lualatex doesn't dump hyphenation patterns in the format, AFAIK.

Ciao
