there's a lot of factors that you aren't including, if there's already a huge gold advantage on the winning team before the guy rage quit, then no it would not be ok to lessen the LP of the winning team. If someone just rage quits after someone (or themselves) gives first blood, that's a hugely different context.
Aye, there are certainly lots of factors.
But If I was good enough to make someone rage after first blood, should I win less LP if I win that 4V5?
Then there are differences in MMR as well that we need to take into account.
Gold differences could be due to just snowballing kills or better management of the minions / denying gold. It could become a factor when calculating the differences.
But before all that, the main question that needs to be asked is "should people be earning less LP if they win a 4v5?"
