Blackbeard knows IMU is in love with Lily and wants to use the Boa’s fruit and a fake Lily to defeat him. The fake Lily would ether be Vivi or Katarina Devon transformed into Vivi, who has the same appearance as Lily and triggers IMU’s lust making him susceptible to Boa’s fruit.
Blackbeard went to steal Boa’s DF for this purpose, but once he saw the Boa Seraphim he realized there was an easier way to gain Boa’s powers through the Seraphim or Greenblood. Which is why he sent Katarina to copy Saturn and I think we have not seen Lafitee because he is going after Vivi.
You might wonder how Blackbeard knows about IMU and Lily. I think he has learned this through his connect to Rocks who was friends with Gloriousa. Being an Amazon Empress of Amazon Lily I think Gloriousa is aware of it’s secret that this is the place Lily hid after betraying IMU and has her account of her relationship with him.
