Q.Did I Ruin My Creeping Fig Ivy?
Landscapers came during the summer to spray weeds and I believe sprayed the ivy killing it. This entire section pictured was dead vine without anymore green ivy. I pruned the entire section and left the thick roots, however I am unsure if I did more damage and am wondering if the vines and leaves with grow back this spring. Or do you think I need to dig up the plant and start with a fresh new one?

Actually, you did what I would have done. Sometimes it is easier for the plant to grow new growth than it is for it to fix dying growth. What you did was probably best.
Proper care and a careful eye will be all that you can do, unless you have not flushed the soil/had a good rain since then.
