Didn't apply to UT, but in general, I avoid that question. Could be unreasonable paranoia, but what does it matter? It should have zero effect. I have a feeling they just want to know what students compare their program to.
When it comes to the funding questions, I always lowball it and assume things will be more expensive than I expect. Santa Barbara's application asked for a dollar amount I could contribute and I thought that was SUPER weird and I was uncomfortable. That was the only application of mine with that specficity.
