My PD included ground meat in her list of things to feed my 9-month-old. My baby looks like she wants to vomit (as if she doesn't like the taste) after a few bites though. Should I keep trying or wait until she's older?

You can mix the ground meat with the thing she likes the most. Keep the quantity of ground meat less so that she gets more taste of the thing that she likes, may be porridge, mashed potato or a cereal. Chances are she would eat it nicely. If it still doesn't work out, let her PD know and may be he can give an option.
