Vent kitchen hood vent to roof turbine vent?
TL;DR: 


It is explicitly not to code to exhaust into the attic or to use foil pipe
It's a bad idea anyway because it puts smoke, grease and warm humid air into your attic which can cause mold growth 




2015 International Residential Code, Chapter 15:


  M1501.1 Outdoor discharge. 
  
  The air removed by every mechanical exhaust system shall be discharged to the 
  outdoors in accordance with Section M1506.3. Air shall not be exhausted into an 
  attic, soffit, ridge vent or crawl space. 


Foil pipe is also not allowed:


  M1503.2 Duct material. 
  Ducts serving range hoods shall be constructed of galvanized steel, stainless 
  steel or copper. 


I'd also say aside from the material, foil pipes don't meed the requirement of having a "smooth interior surface": 


  SECTION M1503 RANGE HOODS 
  
  M1503.1 General. 
  
  Range hoods shall discharge to the outdoors through a duct. The duct serving the 
  hood shall have a smooth interior surface, shall be air tight, shall be equipped 
  with a back-draft damper and shall be independent of all other exhaust systems. 
  Ducts serving range hoods shall not terminate in an attic or crawl space or 
  areas inside the building. 


Also note that range hoods are very explicitly not allowed to exhaust into an attic, though there is an exception for hoods that are specifically built to exhaust elsewhere:


  M1503.1 Exception: Where installed in accordance with the manufacturer&#146;s 
  instructions, and where mechanical or natural ventilation is otherwise 
  provided, listed and labeled ductless range hoods shall not be 
  required to discharge to the outdoors. 




This of course can vary by jurisdiction (eg: your jurisdiction may follow a different version of IRC, have their own amendments, or not follow it at all), and the final call is up to the AHJ (Authority Having Jurisdiction, aka inspector). You can likely call your local building permits department to be sure.
