You can't intelligently design something to violate the laws of physics.
I don't see how the sun reduces entropy simply by giving off energy.
Have you not heard of photosynthesis? The production of sugars from water and carbon dioxide requires negative entropy, and that is driven by the energy coming from the Sun.
Does it reduce entropy on Mars?
Yes. The equator of Mars is warmer than the poles. Any time you have a continuous temperature gradient that is negative entropy, and in the case of the temperature distributions on Mars that negative entropy is driven by the Sun (as it is on Earth).
So it is statistically unlikely that all the molecules in a gas will go into one corner of a jar because there are to many other possible arrangements. So entropy reflects the unlikelihood of certain formations or order when there is a huge range of other probabilistically available outcomes.
Take a look at high and low pressure systems in Earth's atmosphere. Those are driven by the Sun.
