AITA for telling my aunt I couldn’t help with her legal issue?

I’m 23F, finishing my law degree (not from the US so timeline is different) and currently focused on my dissertation. I’m not admitted yet and will be starting at a firm next year, so I’m cautious about what I say regarding legal matters.

I live at home and my aunt visits our home frequently, and most of the time it’s to ask for help understanding something “legal.” She used to do the same with my dad (who isn’t a lawyer), asking him to read judgments and interpret court decisions.

During a recent dinner at our place, she asked me what I was doing this summer and I told her I’m working on my dissertation and balancing that with some time off. She dismissed that and repeated that well you have nothing on so help me with my case. I reiterated that I’m committed to my dissertation.

I still tried to be polite and asked her what the drama was about so she could vent. Instead of answering me, she explained the entire situation to my mother in another language I don’t understand, so I wasn’t able to follow any of it.

After she left, my mum told me I was rude and should have acted more willing to help. She said that if I had sounded more enthusiastic (her example being "yes what is going on tell me so I can help you!!"), my aunt would have spoken in Canto/Mando. She also said I should have offered to “refer her to someone,” even though I don’t know anyone in her area of law and would simply be searching the internet like anyone else.

This isn’t the first time something like this has happened. On a separate occasion, this aunt asked me to find a lawyer for her friend. I found one on Google that seemed reputable and basically told her that they look good based on reviews on GOOGLE, but I can’t personally vouch for them since I don’t know anyone in that field nor anyone who works at that particular firm. My mum said the disclaimer made me sound unhelpful and that I should have just handed over the name with more enthusiasm.

I think a bit of context of my families ethnic background may be relevant? My mum is Asian and grew up with cultural expectations around helping extended family and showing willingness, even if you can’t ultimately do much. My dad is white and I grew up in a Western country, so I tend to communicate more directly which sometimes leads to mismatched expectations between us.

Also, I’ve tried explaining that in law you have to be upfront about your limitations and avoid giving the impression you can guarantee anything, especially when you’re not admitted. But of course, my mum thinks I’m taking things too seriously and that no one would interpret my words that literally, even though on the off chance they did take it seriously, I would be the one bearing the burden, not her.

The disagreement ended up souring the mood in the whole house, and now I’m being treated as though I was rude during dinner.

AITA for being honest about my boundaries and what I can realistically offer?

ETA: I forgot to mention but my aunt is in the business of property investments. She’s hired really expensive lawyers before with cases that have gone up to the Supreme Court. Chucking it in just in case it is relevant.
