It is likely that your conviction will show up on you LEADS report, which can be accessed by any officer in Ohio. And yes, officers do usually glance at this report when running your license during a traffic stop. Any record that is sealed should not show up on the LEADS report.
Much of your questions is abstract and based on the "what if?" of a situation that is unlikely to result in any criminal charges. I understand your apprehension at the way you may be treated based on something that happened over 15 years ago, but no one here will know exactly what the average officer will do in your hypothetical situation. And every officer is different so who knows what one will do given your circumstances.
The reality is that what an officer does and what an officer is allowed to do are two different things. When you encounter law enforcement you should handle them the same no matter what your past or curent situation is. Be polite, give then your information (DL, proof of insurance, registration), and ask to answer any questions with your attorney present. Unless there is reasonable suspicion to detain you further, they can only either write you a ticket or let you go. What you shouldn't do is argue with the officer, refuse to show required information, or anything else that may make the situation worse.
The conviction will most likely show up on a LEADS report that an Officer will see if he pulls you over. He can ask you about it and some will where others will not. There is not a good way to shut them down without making them mad. The best way to take the power away from a bully is to stay calm answer the questions calmly and they will eventually back down. If you become combative and argue with them it will only make things worse. I agree with Attorney Mayo that it is inappropriate and unprofessional for them to belittle you but believe arguing will get you in more trouble than rolling with the punches. Good luck.
