I have a friend who was drugged (date-rape style drug) and convinced to empty his account in an ATM. Woke up in a hospital without any memory of it. Some EU law forces banks to reimburse you when you didn't get the money of your free will - the LLM informed him about it and helped him to fill in all the forms etc and go through the full procedure, which included appealing the bank's negation to the "banco de España". He got his money. I think there are many cases where the LLM can help people that would never have the money to pay lawyers.
