I'm no expert but if the leaves are getting sun, the tomatoes will do just fine. In general, fruits benefit from direct sun but leaf shade doesn't seem to bother the tomatoes. Enjoy!

Tomato fruits can get sunburned (sunscald), especially when the temperatures are over 85F for a while. Different varieties respond differently, and optimally they would not be in killer sunshine. But completely shaded arguably might not be best either since some people say chlorophyll on green tomatoes, especially heirlooms persists a while to help make them sweeter by making more sugars. But unless you are seeing problems on your tomatoes, don't worry about it. People that have problems typically have denuded their plants in response to saving it from some blight, leaving naked fruits in hot sun.

The problem is the Sun is like a microwave oven and can heat up the surface more than the ambient temperature from simple air contact. So the surfaces of the tomatoes' surfaces can near 100 degrees even if the temp is 92F out, like here in Florida. If you don't have a problem, no need to fix it.
