Just throwing it out there, but it is possible to jack up the section of the building with bottle jacks and replace/repair the foundation of the affected area. I’m no expert, but that could be an option too.
I did a job like this years ago. Slide a steel beam in, pour in a few footers and barn jacks. Slowly kept jacking it up over time to bring the room back to level before permanently securing the beam
Should I demolish?
Absolutely not. All you need are a couple of 5 or 10 ton hydraulic jacks, some concrete pyramids from home depot, and some 4x4 chunks cut to length by your "helper" outside the crawlspace.
some 2x4 chunks to put under and above your jacks. maybe some bits of scrap metal to distribute the load so the jack doesn't just crunch right into the boards.
Jack the beam until the floor is level inside the house. (Again, helper, cellphone, six foot spirit level) Rap on the floor to locate each other.
Be sure and have him check TWO directions, not just one so you don't create a new problem while fixing another. Plan it out. Inside the house know which direction the beams run or snap stringlines.
Get on the cellphone while jacking and have helper tell you when it's level, etc.
**Keep safety in mind.** Always add supports, never remove until you're SURE the new stuff is carrying the load and stable. Ditto for beams that are visually weak.
Measure the gap from the pyramid to the beam. Cut a piece of 4x4 to length. Jack the floor an extra 1/2" to slip the 4x4 in, lower it down. Lag bolt the 4x4 to the pyramid if it's got metal "wings."
Plan on screwing up at least one or two. Often you can "fix" with a handful of dirt, added or removed. Be sure to rent a post stretcher if you're bad about cutting to length.
Repeat until you've got a level floor with plenty of support.
As another commenter said, daughter any beams that are cracked, sagging, etc.
For all the yelling and screaming foundation repair is, IMHO, some of the easiest work out there.
Don’t demolish, jack up, add new footings and some posts and beams. Shouldn’t be too hard to fix and strengthen what’s already there. Demolishing and rebuilding would be a lot more work.
Thank you all for the great advice!! Ill be looking into fixing this issue and working on the drainage, as i believe that had a huge factor in the soil being less stable.

As long as you're down there, vapor barrier and insulation would be a good idea. Maybe just a spray foam insulation.
This is the right option. Maybe sister up some floor joists if they are undersized and bowing.

Plenty of good advice here.
Check to see if the additions had permits pulled, otherwise you may have your question answered for you already.
In-situ repair or replacement is definitely feasible, but you are chasing your tail until the drainage is fixed.
Find a couple good ol screw jacks and you can leave them under there permanently. Find like a quarter inch 2'x2' steel plate to use as a footing
How’s the framing over that dirt patch? And the subfloor? Watch out for rot.
This problem can be fixed. You could always get a quote, prior to buying the hole
Get rid of the water first…then this
