    GetDate(),
    @db,              
    EVENTDATA().value('(/EVENT_INSTANCE/EventType)[1]', 'nvarchar(100)'),

MSDN 上的 EVENTDATA状态

仅当直接在 DDL 或登录触发器内部引用时，EVENTDATA 才会返回数据。如果 EVENTDATA 被其他例程调用，则返回 null，即使这些例程由 DDL 或登录触发器调用也是如此。

您上面的触发器是 DML AFTER 触发器。

你需要

CREATE TRIGGER TRG_CreateTable
ON DATABASE 
FOR CREATE_TABLE 
...
