No.

They attract by ordinary gravitation.

Suppose you could do a slingshot with it.

Would a repelling black hole be a proposed white hole

No, they also attract gravitationally.

Agree. Yes, a white hole attracts gravitationally, even though it expels matter rather than gobbling it up. It has a different sort of event horizon, one in which nothing can enter rather than one in which nothing can leave. It’s quite peculiar.

It seems to be a misconception spread by scifi etc… that black holes have some kind of superattractive force that drags everything in.

Gravitationally they behave the same as a star or planet of the same mass.
