I appreciate the input, and it should be obvious that a child on LTR visa can attend school, but the school has a government liaison officer with direct contact that indicates otherwise. I'll be in BKK in a week so will stop by the BOI office to see if they can assist. FYI, not that it's reliable, but an AI query indicated that a child dependent CANNOT attend with just the LTR - not sure what their source was. In any case, I'm still back to the required ED visa $2k in bank question that was my original query. No response to that and local embassy is impossible to contact.
