Now, this particular circuit failed in two ways: One, it was getting laggy, and two, the LED did not light up in the slightest

I think the values of the components need adjusting. It looks like you're going for a capacitive dropper with a second capcitor as a filter, but all you really have is a current limiting resistor. You need to decrease the capacitor at the top to lower the voltage (try 470nF) and decrease the resistor to something that stops things overloading when you're caps are charging (try 100ohm). You're filter cap is also a bit small to do anything (try 47uF).

I'm assuming the led was set to 91V deliberately to represent a string of them that requires 91V, if not just dececrease the top capacitor value until you get the voltage you want.
