Truthfully, I'm still trying to work out how to work out the LORA files. The files were run through Seaart using the Comic Model and Comic Babes checkpoints. It is 70's Byrne, and you're right that the first is better than the second mimicking it. I had a third pic as example, but Civitai pulled it down for some reason.

I did not design it with any trigger words. My thought was that people would use a standard western comic type of checkpoint, or a general checkpoint overall. With some of my past files, people have said using the phrase, "in the style of", like "in the style of john byrne" is helpful.
