I was a little bit confused because I had thought that seg wit had already been activated in Litecoin, but I see that it has not.

Regarding seg wit consensus activation threshold in litecoin, it appears that they have chosen a 75% consensus level for their activation, so yeah, it does seem that chances are pretty decent that seg wit will be activated in litecoin in the near future... so then, possibly that could allow for some development around seg wit and to see how it plays out, at least in terms of litecoin's ecosphere.
