"Rigor"

So I took a “dual credit” US History class at a community college in my area as opposed to taking Apush. However, it is widely known that apush is the more rigorous choice. If I will have taken 15+ AP courses upon graduation, do you think this will significantly hurt me in the eyes of an AO?

No. You have already taken more than they are interested in. They are more interested in how you did in the AP classes than whether you took 15 or 16. I think 8 would be fine, if they were the most important ones.

Out of curiosity, what 15 AP courses will you have taken, and how did that fit in your schedule?

15 jesus mane lol, my school lets you take a max of 10
