Any fees associated with the TCPA would be a matter for the court, not the parties. It's not something that that they can negotiate in a settlement and definitely not in mediation.
eta to pre-empt argument on this point:
The court shall award. The parties don't get to negotiate it.
Mediation can often resemble a settlement discussion, which is where I can see your confusion arising, but settlement has clear delineations of responsiblity, fault, damage and compensation. It is problem-focused, whereas mediation is solution-focused, designed first to bring each of the parties to a point where each party can recognise, understand and empathise with the position of the other parties, then to bring them to a point where they can move beyond asssigning blame and fault, and demanding compensation, to a place where they can propose mutually agreeable solutions to their conflict that result in all parties being able to, if not be friends, then at least be non-hostile, with a view to improving relations in the future. Such matters as compensation rarely enter into the discussion, as that will place barriers to cooperation between the parties.
Again, I'm speaking from (painfully long and drawn out) experience on this matter. Court-ordered mediation is particularly difficult to manage, as it begins with hostile, mutually non-communicative parties who have been in long conflict and who are literally being forced to sit down together and set aside any desire for compensation in order to reach a compromise agreement.
Mediation requires all parties to abandon that idea and focus on mutual solutions. It might "settle" the pending lawsuit (though it should have been ordered at the very start of the case, right after the first motions were submitted - or even before that), but it is not a settlement discussion. Settlement in litigation requires one party to be "wrong" and the other "right" to a greater or lesser degree, with some action taken to settle the imbalance of justice between the wronged party and the wronging party. That is the antithesis of the mediation process.
