I would keep Richmond and Case Western on your list because they both offer merit scholarships up to full tuition (by separate application). Case also has a preprofessional scholars program that offers direct entry into their med school, contingent on maintaining a certain academic standard and there are merit scholarships associated with that option.
These awards are highly competitive and to have a chance, I would try to up that 1430 SAT score (or take the ACT and strive for a 33+)
Of your LAC options, ones that come in under less than 20K might be worth an application as they’re within striking distance of your parents’ contribution, plus student loan, plus summer/part time work. However, the CSS profile may give you different figures than the FAFSA, especially given the foreign investments you have mentioned.
