Yes, they should be held responsible, as they are the responsible legal guardian, and withholding effective treatment from their child is and should be a criminal offence.
Freedom of religion can never trump the right to personal physical integrity. Thus,
as soon as they endanger any non-consenting adults or the life of somebody in their care.
seems an okay formula to me.

There have been a few studies over the years that have linked religious people recovering quicker when they are told that people are praying for them but, that is recovering from surgery or other medical procedures. I'll dig up a link to one of them when I get home.
That is the same placebo effect that occurs when care personnel allot even only as little as five minutes (!) per patient to allow the patient to voice his concerns. The latter change in communicative practice has been found to reduce post operative recovery times by
3 days on average and increase compliance drastically (10.1055/s-2004-837858, etc.). Whatever reduces patient's concerns, be it the announcement of prayer, or proper communication, is bound to help here.
However, that does not imply that it can supplant the actual treatment. It can, if anything, support it at best.
