My kids -two different public schools - research opportunities were there for the taking. They couldn’t find enough kids. I wouldn’t worry about that - especially a school like SDSU. Maybe at a tippy top kids actually want that - but most study, eat, party or have fun, etc. - and aren’t doing research.
I wouldn’t be concerned personally with not getting attention because PhDs are present - but if that’s a concern, then apply to schools without PhD programs - mainly LACs. I don’t think that should be an overriding concern though.
But for each school of interest, have your student reach out to the department head and set up an informational interview. Or - if you are going on visits, have admissions set something up for you - additive to your info session and tour. We did. They’ll gladly answer your questions.
