There is not default method provided in JSOM to create page from template but you can add new client side page and copy everything from template page.

If you able to use PnP Js then you can use Copy method which is being used for copying page.

namespace CreatePageFromTemplate
{
 class Program
 {
	 static void Main(string[] args)
	 {
		 string userName = "email address removed for privacy reasons";
		 string password = "**************";
		 using (ClientContext clientContext = new ClientContext("https://Tenant.sharepoint.com/sites/SiteName"))
		 {
			 SecureString securePassword = new SecureString();
			 foreach (char c in password.ToCharArray())
			 {
				 securePassword.AppendChar(c);
			 }

			 clientContext.AuthenticationMode = ClientAuthenticationMode.Default;
			 clientContext.Credentials = new SharePointOnlineCredentials(userName, securePassword);

			 // Load the template page
			 ClientSidePage page = clientContext.Web.LoadClientSidePage("Templates/MyTemplate.aspx");
