Foundation repair causing stress on house frame?

[Seth Otto V]

I am under contract for a house that has a bowing foundation wall. This is a walk in basement house and it's on a hill. So there is about a foot of foundation uncovered (out of the ground) on the back side and not covered on the front.

A foundation company is recommending powerbraces (fancy I beams) to take the weight of the soil off the wall and evenly distribute it to the floor joists and the rest of the house. I feel like this will cause stress and shifting on the house frame as the only thing that it is secured by is the foundation. A third of the foundation is not even in ground so the only thing supporting it, is itself.

Can someone explain why this is a normal and recommended practice? I couldn't find any research about it online
