Is there any point in an epileptic continuing to see a doctor who thinks an EEG is definitive, denies the seizure triggers?

Second opinion. Many patients become uncomfortable with their doctors. It is reasonable to request a second opinion. It is also very important to discuss you concerns with your doctor so that he can help you understand his opinions and his mode of treatment. Often after a good thorough discussion, the appropriate treatment program can be developed that both of you agree to.
