PieSlice outside (default) label underline has a fixed white color - it's not affected by labelColor and doesn't seem to have its own color property.
Minimal reproducible example:

import QtQuick
import QtGraphs

Window {
  width: 640
  height: 480
  visible: true
  title: qsTr("Graphs 2D - Pie Graph")

  GraphsView {
    id: graphsView

    anchors.fill: parent

    PieSeries {
      id: pieSeries

      PieSlice {
        value: 1
        labelColor: "red"
        label: "label"
        labelVisible: true
      }
    }
  }
}

PieSeries "valuesMultiplier" property has no effect. While it's difficult to say how this property would affect a pie graph, a note in the documentation regarding for which graph type this property is valid would be beneficial for documentation strictness.
Minimal reproducible example:

import QtQuick
import QtGraphs

Window {
  width: 640
  height: 480
  visible: true
  title: qsTr("Graphs 2D - Pie Graph")

  GraphsView {
    id: graphsView

    anchors.fill: parent

    PieSeries {
      id: pieSeries

      NumberAnimation on valuesMultiplier { from: 0; to: 1.0; duration: 1000; easing.type: Easing.InOutQuad }

      PieSlice {
        value: 1
      }
    }
  }
}

PieSeries "selectable" and "hoverable" inherited properties are present but no "selected" nor "hovered".

PieSlice label is not affected by label related properties in GraphsTheme.
PieSlice border is not affected by "borderWidth" defined in GraphsTheme.
Minimal reproducible example:

import QtQuick
import QtGraphs

Window {
  width: 640
  height: 480
  visible: true
  title: qsTr("Graphs 2D - Pie Graph")

  GraphsView {
    id: graphsView

    anchors.fill: parent

    theme: GraphsTheme {
      labelBackgroundVisible: true
      labelBackgroundColor: "yellow"
      labelTextColor: "red"
      labelFont: Qt.font({
                           "pixelSize" : 24,
                           "family" : "Roboto",
                           "weight" : Font.Medium
                         })
      borderWidth: 5
      borderColors: ["red"]
    }

    PieSeries {
      id: pieSeries

      PieSlice {
        value: 1
        labelVisible: true
        label: "A label"
      }
    }
  }
}
