what does a normal tsh, low t4 and low t3 (liothyronine) mean?

Perhaps nothing: Such tests need to be repeated. If the T4 and T3 (liothyronine) were measured as total T4 & T3 (liothyronine) it may mean only that the binding proteins of thyroid hormone are low. Ask your doctor what was done and his/her interpretation.
