@michaelnissenbaum within the Global search menu is adding the aria-live attribute necessary to pass the accessibility audit?

The question here is where and for what your are planning to use aria-live attribute. As I can see you plan to use an autocomplete search, that means you type a character into the field and below search results are shown automatically. In this case I'd not recommend use of aria-live as you can overload screen reader users with information. Except after every character you will wait some time till information is provided to aria-live container - and then only let users know how many results are found, but not read all the results. My suggestion would be to make it working without aria-live, e.g. using aria-describedby attribute on input field in order to let users know what they could expect - e.g. "the search process starts automatically once you put search text into the field and results could be reached be arrow keys". See e.g. how comboboxes with autocomplete are implemented using ARIA - https://www.w3.org/WAI/ARIA/apg/example-index/combobox/combobox-autocomplete-list.html.
