My theory is that it’s due to the tonal ambiguity in writing short messages.
In longer form writing, it’s easier to establish a tone. But with something like a text message, it’s harder to convey, and it’s easier to accidentally come across as being short or harsh. The trailing “lol” is like a little flag that says “hey, we’re friends, and I’m not taking this too seriously, and I’m not mad or offended or anything!”
Just a theory though lol

I always love this sign, because what is calling 911 going to do? You might as well stand there and lol, the EMTs ain’t getting there in time to save them.
It’s so you don’t take the blame for their death. They weren’t dead yet when you called.
