Child's Mother Refusing Parenting Class

Location: KY // I am step mom, and my husband and the child's (4 year old) birth mother had a court hearing about a month ago. The judge ordered both of them, not just one parent, to take coparenting classes due to continued arguments and disagreements in their court-mandated app, AppClose. My husband is almost done with the classes. The child's birth mother claims that the co-parenting classes are for my husband only, since she has three other kids and she thinks she knows what she is doing. My husband and I are concerned she will not go to the co-parenting class, and there will be no penalty or, worse yet, resolution for the child. Assuming she does not attend the co-parenting class, can my husband have the birth mother summoned to court to pay a fine without having to pay his attorney another $4000 retainer for the judge to do practically nothing? Do they let the judge know she didn't attend, and then no action is needed on his part?

For context why this is important: He is having behavioral problems in school, and she is refusing for him to see a child psychologist or get screened for autism/ADHD. Anytime my step son has a problem, she automatically blames us and says our home is "full of hate." She is highly triggered anytime a doctor is mentioned, even a routine pediatrician visit. I have concerns my step son is not well cared for in her home. When he comes back to us, he is severely tired and we can barely enjoy him because he has to catch up on sleep. She puts him in clothes that are too small, even though we have sent him in clothes that fit. She keeps those for herself and keeps giving us the ones that are too small. My husband offered to buy my step son clothes for her house and she refused. They can't even discuss clothes without a showdown in that court app, and I'm concerned my step son's needs will not be met and he will severely hurt another child biting them. At the very least, I feel she should be penalized for the poor behavior within the court app to encourage more fruitful communication and co-parenting efforts in the future.
