Hello @jgreenberg,
Thanks for asking. 
You have the option to add following CSS under Pro > Theme Options > CSS to hide author box in product page:
.single-product .x-author-box {
display: none !important;
}
Please note that custom CSS and PHP solutions falls outside the scope of support we offer. I shared above CSS and PHP codes to help you get started. Please note that in case of any issues, we wonโt be able to provide support for the same.
That being said I have used CSS to hide Author info in product page. If you would like to explore and learn CSS then please take a look at following resources:

Sometimes it can get a bit difficult to find out the right selector to be able to write the required CSS codes. A handy tool that can help you in this is Google Chrome dev tools. I am sharing the resource that you can refer to get started with dev tools.
