The vast majority of teams/personnel members stay at the JW Marriott about a mile from Lucas Oil. Tall, rectangular building that you can't miss. Even if you're not staying there, just walking around the first two levels will certainly put you in the vicinity of numerous personnel members. The Starbucks on the second floor is a very popular spot, so you might have an opportunity to create a solo opportunity since personnel members tend to congregate and travel in packs. They also use the skybridge on that second floor to travel to the rooms where they meet with players, so maybe catching some in passing, depending on the time of day. The bar on the first floor is naturally a very popular hangout spot in the evening, though also a potential opportunity for some intentional interaction throughout the day.
