I have this small problem that really bugs me, haha. Do you have any suggestions on how to fill in the gap under the door trim without spending too much money? Also, thank you to everyone who suggested using a shoe for the same spot. Check out the picture of the shoe in the comments.

Trim down the baseboard and cut the casing to fit a 5-1/2” x 5-1/2” chunk of 5/4 for a plinth block appearance
This is what we ended up doing after replacing the flooring – all of the door jams were too short.
I am going to hang new trim…it’s only $20!
A quarter round is perfect for the floor. I think updating the casing would be a budget-friendly improvement.
Try installing a 1×3 flat plinth block that is slightly taller than the base, by about 1/2 inch.
Has experience doing this multiple times for customers. He trims up dresses a bit and solves the problem!
Remove and replace the new door trim, then trim it to the right size.
You can purchase a professional pack door casing set at Home Depot for a reasonable price. It includes 2 side pieces and a top piece. It only takes about 7 minutes for someone without experience to cut and put it in place.
Change the door casing to ones that go all the way down to the floor.
Simply remove the casing and trim new ones to size.
When replacing the door trim, avoid cutting it into blocks to fit the gap as it often looks messy. It’s better to fix it properly.
Has added plinths multiple times. It has never turned out poorly. His customers always appreciate it!
Why not purchase new molding and recut it to the appropriate size? It shouldn’t cost more than $20.
Seems like a simple fix. Try finding a matching piece and cutting the two existing ones higher up to insert the new piece. You could also just replace it altogether, or use a plinth block. All of these options cost less than $20.
Remove the trim and put in a new one, super simple.
You can find a small gap filler at Home Depot. Also, there’s a small square piece made of the same material as the door strip. It’s inexpensive, but it’s the right way to fill that gap.
Try out the new casing. Focus on the side legs first. It’s quick and the easiest way to do it.
Purchase new trim pieces and redo the whole thing
Just glue a piece there, then fill, sand, and paint. Finished.
If the threshold has visible screws, try turning them counterclockwise to raise it. A lot of them can be adjusted.
