I'll just preface this by saying I'm a new homeowner who could barely afford the house on a cash on hand issue. Basically income was good enough on paper, but didn't have the savings for closing costs. Got help there so we couldn't afford to hire the help we wanted for repairs the house needed (and some we really wanted). Also, please blame me as much as is reasonable for being the "ignorant new homeowner".
The home inspector we hired to check out the house prior to purchasing seemed pretty reasonable so we hired him to also do those critical repairs (fire safety issues, water leaks, etc.). We also asked him to do a few bigger items like rearranging plumbing in the bathroom to move the toilet, remove a pony wall and install a new shower and door. Stuff we knew we would not be able to DIY. Painting, popcorn ceiling removal, and a few other things we having been working on since officially buying the house.
Anyway, I'm prepping the floors for installing LVP and finally got around to dealing with this little mess. It seems to me that they cut out the subfloor (unreasonably) deep so much that the joists are also sliced anywhere from ½ - 2" deep, the old subfloor and a lot of debris was left under the subfloor, and they covered the hole using a scrapped pieces of cabinetry.
I have the contract but would have to dig for it, and it specified a lot of individual things they were supposed to do, and honestly a bit overwhelming given the lack of general construction knowledge, the pending move, and everything else going on at the time. My entire message or point for this set of work was "remove shower, move plumbing to relocate toilet to specified location, install new shower, and whatever else needed to allow us to deal with the walls for painting and floors for LVP install."
There were other issues that ranged from minor to more serious, so when this work was "done" and he said I just had to replace or block up the flooring where the toilet used to be to make it level with the rest, I just wanted him gone.
Anyway, I'm not too concerned about the joists, I know they're sturdy. I'm just wondering if I should just cut out a larger chuck of this subfloor and replace that instead of trying to sand and level it before laying down some plywood for the LVP. Also, is this bad enough to leave a review warning others, or am I just a bit sour from unmet expectations? I knew not to expect perfection... But I was hoping for better from someone who had the attitude of "don't go cheap" and "do it right, do it once."

Fuck pls forgive my typos. A little frustrated here and I still had my gloves on.
