AITA for not participating in the meal train?

I got a text from a friend on Sunday saying she’d had a sudden abdominal surgery. She also sent me a link to a meal train for her family of five. I asked her how she’s healing today and again sent me the meal train sign up. They are gluten free. This is a friend I was closer with 20 years ago but now we get together once every few months. I don’t know her husband or kids enough to know their likes and dislikes. I’m single and work 40+ hours per week yet still live paycheck to paycheck. This friend has both parents and in laws right here as well as two adult sisters. I don’t really have time for this. My sister who has had a couple c-sections thinks the whole idea is ludicrous and friend is reaching with this request. Her husband or their teenagers are capable of throwing something in the oven.
