I am sorry to learn of this situation and complex series of events.
It appears that this attorney has indeed complicated matters by forcing a trust into probate (sometimes a trust does need to go to probate, but one of the primary reasons for using a trust is to avoid this procedure).
However, if the matter is in probate, it does have to exit probate.
Unfortunately by not going to court, you may have missed critical steps in the probate procedure (whenever there is a hearing on a matter that you are involved in, make sure that you appear - even if you are unsure of what is going on at the hearing, show up - if nothing else, you can ask for a continuance to prepare an argument on the issue and come back to argue it later).
The attorney messed up, and they should be the ones that make it right. They should do so at their expense.
You may have a legal malpractice case against this attorney - but unfortunately, this matter is likely too small to be worth pursuing in general civil court. You can consider hiring a local malpractice attorney for the purpose of writing to the attorney and threatening suit, with the idea that this first attorney (the one that filed probate without needing to) will both close out the probate at his expense, and reimburse you for any money that you have to pay the malpractice lawyer).
Do not rely on your "Legal Shield" account - I understand that a lot of people use this service - I cannot recommend them. (I know we cannot provide specific referrals on this site, but if you want effective legal representation, go to a local attorney). You can find local attorneys using the State and local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).
Unfortunately working out the details regarding an argument for why you should be compensated (this should be easily done), and how exactly the probate should be closed out - are things that are going to rely on a specific review of your documents (the trust and the probate action itself), which a local attorney will need to do - but given the scope of your efforts, you should be compensated as your fees appear "reasonable" - and you should be compensated as an "administrator" (whether or not you are identified as the administrator is an issue that is going to be key here - and if you are not, the attorney is going to need to show why not).
