Sent ltc to kucoin btc address accidentally

Few years ago i accidently sent quite a bit of litecoin to my kucoin Btc address accidentally. The network automatically created a ltc address based off my kucoin Btc address and the coins have been on that ltc address for roughly 2 years . Id have to imagine there has to be a way kucoin can get the funds recovered because they DO NOT provide the secret keys to the funds stored on their exchange . If Anyone has any insight on how to HONESTLY recover the funds and walk me through the process I will donate as a way to thank u
