                    alignmentFocus: go.Spot.Left

                },


                $("TreeExpanderButton", // support expanding/collapsing subtrees
                    {
                        width: 14,
                        height: 14,

                $(go.Panel, "Horizontal", {
                        position: new go.Point(18, 0)

                    },
                $(go.Shape, "LineV",
                    new go.Binding("visible", "toNode", function (n) {
                        if (n.data.brush) return n.data.brush;
                        return "lightgray";
                    }).ofObject(),
                    {  stroke: "lightgray", width: 1,
                        height: 25

                    }
                ),

                $(go.Shape, "LineH", {
                    width: 13,
                    height: 22,
                    stroke: "lightgray"


                }

                ),

                    $(go.TextBlock,
                        {margin: 2, name: "MAINTXT" },
                        new go.Binding("isUnderline", "underline"),
                        //new go.Binding("font", "bold"),



                        {font: '8pt Verdana, sans-serif', margin: 8},
                        new go.Binding('margin', 'isTreeLeaf', function (leaf) {
                            return leaf ? leafMargin : 5;
                        }).ofObject(),
                        new go.Binding("text"))



                ),

Add:

new Binding('visible', 'isTreeLeaf', function(isLeaf) { return isLeaf; }).ofObject(),

to the lineV:

$(go.Shape, "LineV",
    new go.Binding("visible", "toNode", function (n) {
        if (n.data.brush) return n.data.brush;
        return "lightgray";
    }).ofObject(),
    new Binding('visible', 'isTreeLeaf', function(isLeaf) { return isLeaf; }).ofObject(),
    {  stroke: "lightgray", width: 1,
        height: 25

    }
),

Note that you have this other “visible” binding too, I’m not sure the purpose of it but it may conflict.

That first “visible” Binding can’t be right. GraphObject.visible is a boolean property, so the converter cannot return a string.
