In one of the most recent articles Trent is asked about Billie Eilish. He mentions that he hasn't really listened to her music, but that Atticus has and kind of dug it, so he needs to look into it for himself.

I know I'm daydreaming here, but I would LOVE it if he gave her music a shot, liked it and tried to do something with her musically. Even if just one song. Billie is like ALMOST there for me, the lyrics can be a bit silly at times. But she's so young that I feel like it's not worth nitpicking over. Her image is cool as hell, her voice is wonderful and she seems willing to explore new sounds and try anything.

I feel like a bit of guidance from somebody like Trent would result in amazing growth for her, as well as her brother who shows a lot of promise in terms of his production work.
