it is called Electrum not Electron (just in case you are using a false wallet, do a double check).
and in case you have your wallet files and if you are lucky and you have not encrypted them with a password, you can easily open your wallet file in a text editor and see its content (not sure how the old .dat file worked though).
in that you can see your Seed phrase, your addresses, your tx, and your private keys.
Thanks. It turns out I was in the wrong wallet! I downloaded Litecoin Core, updated the blockchain (almost 6 years worth!) and boom! there were my coins. Cheers everyone!
