But did split the vote in seats the Torys could have won.

Debatable,

Yep, no obvious analysis of the final vote count that I can find.

a lot of disillusioned Labour voters wouldn't vote
Conservative under any circumstances but a vote
for the BREXIT party may attract those votes

Yes, but without a brexit party candidate standing
those would likely not bother to vote. Its very far
from clear that Farage prancing around their seats
made them consider not voting for Labour at all.

and let the Conservative candidate win without having
to increase their percentage vote from last time.

Yes, but see above.
