Can 30 year old viburnum along a home cause foundation damage?

Trying to figure out a moisture issue in a home. It seems unlikely (to me) that a home would have widespread moisture issues “simply” from settling over 40 years. There is a large viburnum hedge along 1 side of the home and about 20 feet of another (making a corner). The other rooms affected do not have large hedges along the exterior walls. Some do have hedges with smaller root balls, but some have no hedge. One of the rooms with a moisture issue is on the other side of the home and it seems to be more of the interior of the room than the exterior. The rooms between the side of the home with the hedge and the opposite side of the home seem to been unaffected, so it seems unlikely (again, to me), that it would be from roots traveling under the home. Some of the tiles in the mostly unused bathroom between the 2 more affected bedrooms are popping up around the toilet. The laundry room (also in between the bedrooms) next to the bathroom, appears fine. However, the dryer exhaust pipe to the exterior was rusted out and the stucco/concrete surrounding it has disintegrated. The home absolutely has unmaintained stucco issues, especially on the more problematic side of the home. The yard also seems to hold water against the exterior wall on that side of the home after a heavy rain.

I’m unsure what type of pipes the home has. It was built in 1989. I don’t think it’s a pipe issue, because the water meter isn’t running when the faucets are turned off. The home is in Central Florida, but has never flooded and is on the “high side” of the street. None of the other homes seem to have the same issue. Don’t know that it matters, but the pool (on the other side of the home from the majority of the apparent moisture) has been patched in multiple places over the years.

Is it possible that the stucco issues/cracks are allowing water to be absorbed/infiltrate and then run on top of the foundation between the tile/carpet and the foundation? Any potential thoughts would be greatly appreciated. The home belongs to an elderly veteran with dementia who is struggling. Hoping someone can help us, help him…
