If the flights are cancelled and don't operate, then Lufthansa should refund your money.
If they continue to insist on "no refund" then a credit card chargeback should do the trick.
If the flights operate but you don't want to travel, then you're into the realm of travel insurance or taking whatever voucher LH offers.
