I'm so confused

All I know is that about 5 months ago, one of my bulbs for the side marker went out, so I replaced both side markers with LED bulbs.
Also changed out my dome and door lights with LED bulbs as well.
Everything seemed to work fine until just last weekend, I noticed my side markers pulsating like a disco ball.

I'm wondering if it's the bulb going bad, or is it the lack of me not changing the relay to compensate for the LED replacements...

No worries. The relay is fine, its the local circuit that needs more load.

You need to use an filament bulb. LED bulbs have a 50% chance of working and if they work they work incorrectly for the use most of the time.

LED Light emitting diodes act like a "light emitting" check valve. Filament bulbs work like a water dam. LEDs don't restrict, filaments do. Now your issue is that you don't restrict the current enough. This is where most of the time you need something custom.

That's what power resistors are for.
Add them in parallel only. A series connection will dim an LED bulb that is already designed for 12V use.

Side markers on this car do not function as blinkers, so the point is moot. There is no relay and it's not a turn signal. Dubaday has a failing LED side marker that is flickering. A resistor will not fix that.

replacing them with a new one did the trick
(old one top, new on bottom)
