One thing I want to ask about this quote "confirm or deny a withdrawal of 108.5335 LTC from my account"
Did you have exactly this amount of LTC in your account? Yes or No, then you can go from there.
I had 103 LTC. 600 FTC.
The "hacker" changed my feathercoin to btc, then bought an extra 5.35 litecoin with the bitcoin. But at the end of all of that I had exactly 108.5335 which is now all gone. So whoever has done it took everything.
