Laudna is a strange case for resurrections, but the Delilah factor does sort of balance out with "The 30 year victim of the the Delilah" factor. So I guess it depends on how they plead their case, and some good rolls. Keyleth also clearly does not have the resistance to attempted resurrections that people thought she would; she did attempt them on Derek and Will but they failed. That said, I guess the "solution" for Laudna will likely depend on if (due to Delilah shenanigans) she happened to be a Hallow One with her soul still bound to her body; or if she's a standard Hallow One.

But, assuming Marisha wants to continue playing Laudna, I'm sure Matt will find a way. I guess it also depends on who "loose" he wants to be with his interpretation of "soul". Given, y'know, we have a sentient robot in the party as well. Plus, he did just dump like 5k short of a True Resurrection on them today. I don't think the Nien even had close to that level of liquid capital all at once.
