Really.
A lawyer?
Not worth the costs and aggravation for getting such a device activated.
The costs of a lawyer and legal fees will far exceed the costs of the device.
Also, the FBI couldn't get Apple to break user Activation Lock on its own devices for law enforcement purposes.
So, what chance do you really think a lawyer is going to be able to do for you to affect some solution or you?
Just forget this device and purchase a proper iPad on your own.
You can purchase a brand new base model iPads for much less than the costs a lawyer and all of the various legai fees.
Also, Apple has more money than dirt, in its financial coffers, to fight any type of legai battles.
Especially small claims legal battles.
A lawyer will not help you, but just take/siphon more of your hard earned money away from you.
There is simply nothing to be done here.
Do what you will.
