Seems like LTC already implemented this Lightning Network it gives a faster and more reliable transactions compare to the other coins out there.
Where do you heard/read that? (I'm really interested.)
As far as I know, there are tests (the most prominent one having occured in November, when the first LTC/BTC swap was tested), but Litecoin is in no way more advanced than Bitcoin and other coins that have Segwit enabled and the technology is still not ready for mass adoption.
(I would be happy if you were correct.)
