Bike for long legs & short torso?

In general women have longer legs and shorter torso compared to men.

You may want to look at some of the women specific tri bikes.

Overall best way to buy a bike is get a fit for what a custom bike would be measurement and geometry wise and see which frames are closest to that.

I ride women road bikes but my Kuota K Factor fits me out of the box w/o changing the stem. If it is a  tri bike they tend to be designed to fit men unless they state they are women's tri bike.

Have fun looking at bikes! 

Honestly, you're in Houston, so please go talk with Philip Shama at Shama cycles.  He specializes in custom Guru's but carries a few other brands as well. He won't BS you, but he will try to sell you a bike!

Like you, I have long legs and a short torso.  Based on my measurements, no standard frame fit me well, but several could be made to fit me with some creative use of stems, spacers and such.  At the end of the day, I went with a custom Guru that fits me like a glove.  The geometry is not even close to anything on the market, and I'm so happy with the decision I made.  Also, don't think that custom has to mean expensive...some very reasonably priced frames by Guru. My wife just got the Magis, which is priced in the $2000s. 

Regardless, even if you don't buy a bike from him, I'd suggest talking with him.
