You are refering to something I did cover already.
N-VL29, that Lithuanians have it at 93% among N is shared with Mari. I clearly refered to period of history before arrival of Lithuanians in Lithuania. You should, too
Yeah, I'm using a bit loose terminology, but ancient Mari is closest to core of Finnic languages. I find it funny, that talking about contacts of Baltic and Finnic, that happened ~3000BP, people can distinguish Mordvian influences even before Mordvians came into existence... Also, I was not referring to Modern Mari and Mordvian influences, so you should not, too.
There is no such Mordvin language, but there exists Mordvin LANGUAGES - Erzya and Moksha are most used. So, a million dollar question for you: From which ones - Erzya or Moksha Lithuanians have those loanwords?
