If radius guess of a star was wrong and it was 50 percnt larger how would this error affect brightness dip when the planet transits its star?

The dip is OBSERVED. It wouldn't be affected at all. However if the star is larger than it was thought to be, then the planet must also be larger than it was thought to be.

That is the radius becomes 1.5 times - its luminosity will become 2.25 = 1.5² times (and so also its brightness).

Dip in brightness is observed, not calculated from some hypothetical or theoretical maximum.
