Unsure on my non-science LOR PI strength

So my PI, who was also a teacher for one of my non-science classes, recently agreed to write a letter of recommendation. However, I remember when I wanted to do a thesis statement (cause I thought it'd help with med school) she mentioned strongly how medical school is very expensive, difficult to get into and how me doing research is a much safer route and one I should definitely consider. This reminds me of one post on SDN where their letter writer wrote a weak LOR on purpose as they wanted... Unsure on my non-science LOR PI strength
