She gave you the right advice as an immigration lawyer it was her right advice to tell you, like it or not, you should get your AP or not got out with the proper authorized travel document.
That you did not like her answer, is something different. You want a lawyer that were more on your understanding of your feelings...but she was not and is your right to call for a more suitable lawyer for you but is not right to say that she gave you a wrong advice, she did not. Now is funny, you said all that, and that's why many people want to sue others when their lawyers don't practice correctly the law.
Would be good if you can clarify all of us what was "this document" that the IO at the port of entry used or gave it to you. As in all cases is in the immigrant to proof the situations and factors that cause the different actions in question.
I am sorry, for me, you got lucky. Simple as that. There have been pretty sad stories about travel ordeals. By the way, each case is different. I just recall that even uscis give a warning about it.

And if you read "carefully" states that "Travel outside of the United States without advance parole may result in serious consequences including being unable to return to the United States and having pending immigration-related applications denied"...the key is "may result"...well yes, but here is very discretionable...and most of the time is better to go on the safe net.
I dont think that will be a responsible act to say a person "sure go out" would you? For many a lot is at stake and has nothing to do about "dying" to be here. Our advices came from past experience, experience of family and friends and so be it most of the time people before post here don't read many of the instructions on the forms, don't want to listen to what a fourth lawyer keep saying to them or what even uscis is requesting from them. You already had your set minded that if you were not able to return you would not care, so why the fuzz with the lawyer...you try to enter right? lucky for you, you and your family were able to go through. But would you give that same advice to other person...to just go out like that?
Austriacus gave a pretty apple vs apple example. Engineers, lawyers, doctors, accountants are professions that are very well regulated under the law. Don't you wonder why there is always one of them getting sue in this country, apart from the goverment?
If your lawyer told you "yes, go ahead go out and at the POE they will give you a parole" she would be at fault. And if you won't be able to come in (even if you don't care) you most probably would have all the right to sue her for bad practice.
At the end , even you pay for their service to give advice and opinions, people should be responsible for their own decisions. Unfortunately we live in a society that more and more is easy to pinpointing other person for our own fault when things don't go in our way.
I won't give you any example because none will satisfy you and I won't try to convince you, every person is responsible for their own choices. But I would tell you be careful to give an advice when 1. you can't remember or reproduce the paperwork that the IO at the port of entry give to you 2. which part the law states so 3. did you went to another lawyer and gave you a different advice from your previous lawyer? 4. it's really against the warning that had been posted several times in uscis.gov about travel outside the US.
Just wonder if your lawyer or you use your lawyer to give you steps about how to convince your uscis office about that you needed an emergency advance parole. I found other posts about people got their emergency advance parole when they showed notices from the doctors and the funeral home.
My 2 cents, better say...it's like 10 bucks.
