How come LED Light Bulbs only last for about 2-3 Years?
I’ve bought and replaced a lot of light bulbs, and I noticed that all of them said “up to 20,000 hours” which would be about 5 years given 12 hours of daily use (which we definitely don’t).

No, shorting a dead LED in a series chain of 10-20 will NOT burn your house down, it’s barely a difference to the driving circuit. Unless you’re buying knockoffs, there is a fuse in the base that will blow at like 0.5 A, no matter what you do to the circuitry.
In many bulbs, you can adjust the value of a current-sensing resistor (usually one or two in parallel, about 2-30 Ω) to make your own “Dooby” lamp with lower power and way longer life. Of course, you need to know something about electronics.
