Here's what I see you saying:
P1: A patient with psychosis will improve with medications.
P2: A patient with psychosis will not improve with psychotherapy.
P3: Medications change brain chemistry.
C: Therefore, a patient with psychosis has a problem with brain chemistry.
My point is that this conclusion does not flow logically from the premises. It sounds reasonable but doesn't need to be true. We know that meds can improve psychotic symptoms, but that doesn't mean that the psychosis was caused by some neurochemical imbalance.

This is not what I was saying, btw, and I don't believe it's something we know to be true either. Certainly the idea that SSRIs treat a chemical imbalances is outdated and not well supported.
Concerning therapy, different therapeutic modalities are based on different psychological models of what's caused or is perpetuating the issue. Based on these models, a treatment would then be implemented, but the success of these treatments should not be mistaken for the validity of these models. That is, just because a therapy works doesn't mean it actually addressed or even illuminated the actual underlying cause.
In fact, my view on medications and therapy can be explained in this analogy, which I thought of now while sick and medicated, so please excuse me if it's more terrible than I imagine. If you have a bug infestation in your house, say of ants or bees or termites, one solution is to call in the exterminator to spray your house with poisons. That will fix the problem, but that doesn't mean your home's air had a chemical imbalances before with too little poison. And while it worked, it didn't do so by fixing the root cause -- that your house wasn't fully sealed from the outside and had bug food inside.
Similarly, meds and therapy can both work for certain issues (and for other issues, either meds or therapy would work but not the other), and both can induce changes in the brain, but that doesn't mean either treatment is fixing the problem that led to the disorder in the first place. They might, but proving that would require evidence other than treatment efficacy.
