It's bad enough that we have so many sad posts about people losing chickens to a neighborhood dog roaming about.
And people wonder why I just take care if it myself. I don't ask permission, I don't threaten, I don't engage in anything but defense of my girls on my property. You never, repeat NEVER know what you are facing.
People being what they are, or what I've experienced them to be for myself, I am on the same page with you.
aart, I think sometimes, it helps others to get an idea how to handle a situation by what different folks have done, and they can also figure what not to do.
To the OP, they offered to pay for "some" of the hens? No way I'd accept that. They'd pay for ALL of the dead hens their dog killed, all, every last one of them. I'm so sorry you had to deal with this.
That said, you mentioned your pen being inadequate, but even with Fort Knox and fencing, motivated dogs can find a way in if their prey drive is strong enough. My birds are 100% safe when they are in the barn with the door closed (steel barn, locked doors, hardware cloth screens over every window), but the moment the door opens, they are in the barn pen, which is very large and over 5' tall, but they are more vulnerable. When they leave the barn pen, they are within the 2 acre perimeter fenced area, which includes our house, gardens and all other outbuildings. They are more vulnerable then because the livestock fencing is not as tall as the barn fence. My point is that we have done a lot, spent a lot, to keep our birds as safe as possible, while still allowing them free range time when we are able. So any dog motivated enough to get through all that is always going to come back if he's not eliminated, I'm afraid.
Last winter two dogs we didn't know were repeatedly caught on game camera at the perimeter fence. They came back and came back until one morning, somehow, they found their way into the perimeter. Thankfully, the chickens were still inside the barn, it was so early. My husband was stalking them with his shotgun, they were running scared to death. They got separated, one faced off with him, though it was a good distance and he fired. It yelped, but he only had birdshot and at that distance, maybe it just stung a lot. That dog zipped around the fence and found his way out. The other one could not remember where he got in and was running like a scared rabbit all over the place until he finally climbed over the fence and was gone like a shot. They never came back and I still don't know where they belonged or if they were dumpees. That's the way most places in the country are, folks are fairly far apart, can't see who owns what dog, where the dogs go when they run away, etc. You have the misfortune of knowing who the dog belongs to and have chosen to deal with them.
Here are the dogs caught on game camera and the threats made against me when I was only trying to locate the owners:

Every person must make his/her own choice about how that will go down. We already have, after this crazy situation that happened a few years ago with a neighbor. Because of how we were threatened by this person, it has cemented our resolve to avoid speaking to neighbors about their roaming dogs:
