How does litecore-lib set the value of fee, will it keep 0.001?

I believe that is the default fee that is set if you don't provide your own transaction fees. Also, note that the min fee required for a Litecoin transaction also called as the "Relay fee" is 0.001 LTC. If you want to override this default fee just add .fee('your fees in satoshis') to your transaction.

Refer to this link https://github.com/bitpay/bitcore-lib/blob/master/docs/transaction.md

Hope this helps.
