I think your best hope is the police. In Japan though for Mt Gox it took quite some time to get the money back from robbers.

Could you add a Liquid address also? I will send you $10 worth of bitcoins. I hope you will get through this. You remind me the guy who got stolen $800 000 worth of bitcoins last year.

Just from my perspective, in Japan we apologize for sure but the way people in Europe manage responsibility can be quite... irresponsible. Or they shift the responsibility to someone else... In my case I had a 2 million dollars bug but fortunately it was fiat so it was relatively quickly reversible, and I apologized multiple times. I also got new white hairs... It is easier said than done and a painful lesson but when thinking about software engineering I think we should remind us of examples like a rocket which blew up in the air because of a bug related to the type of a number (it was in a CS book but will find the reference if you are interested). This to say that software will inevitably have bugs, and even small changes can lead to critical bugs. So for Lightning, the only way to manage it in my opinion is to be prepared to lose money and to only put in it a part which we can lose. But of course risk management differs depending on everyone and I don't want to blame you.
