Check out the companions from BG1 and 2. They are purposefully not optimized.
Not in this way. They had suboptimal builds, low stats, or strange stat arrays for their class-this is just poor bookkeeping. No one would intentionally build this way-if t were a plot point that you had a low stat, you would either directly and obviously gimp it or not put a bonus in it at all. She effectively gets nothing for that point; it would make more sense for her to have an 8 DEX and a 14 CON instead if she was supposed to be clumsy.
