Because -
  • Roth was the Pied piper! beating the drums! calling the tune!
  • Roth already had the Havana business
  • so much money was at stake for Michael not Roth
  • Roth had Michael believing Michael was Roth's son -- Roth's successor -- Roth's heir apparent

I too reckon, neither Roth nor Ola were after any information from Fredo at all whether it be the Havana deal or Pentangeli-Rosatos meeting because I too believe, both Roth and Ola knew / would have known, Fredo didn't / wouldn't have any -- Roth didn't need any!
