To draw text to canvas, you can do like this

@Composable
fun DrawText() {
    val paint = Paint().asFrameworkPaint()
    Canvas(modifier = Modifier.fillMaxSize()) {
        paint.apply {
            isAntiAlias = true
            textSize = 24f
            typeface = Typeface.create(Typeface.DEFAULT, Typeface.BOLD) // your typeface

            //other methods like color, dither, fontMetrics, shadow etc...are also available 

        }

        drawIntoCanvas {
            it.nativeCanvas.drawText("Hello World", size.width/2, size.height/2, paint)
        }
    }
}

I think to convert TextStyle(compose library) to typeface will be a pain since no support from android, If you want to draw text to canvas I think this will be enough
