Does anyone have a script that utilizes a CSV to create text layers?

This reads line by line rather than use a CSVfile, but it does what you ask.

#target photoshop

addText();

function addText(){
    if(documents.length > 0){
        var originalDialogMode = app.displayDialogs;
        app.displayDialogs = DialogModes.ERROR;
        var originalRulerUnits = preferences.rulerUnits;
        preferences.rulerUnits = Units.PIXELS;
        try{
            var testFile = new File('~/Desktop').openDlg('Select import file', '*.txt');
            if(testFile != null){
                testFile.open('r');
                var textLine = testFile.readln();
                var docRef = activeDocument;
                var LayerRef = null;
                var TextRef = null;
                var pos = 200;
                while(textLine != ''){ //read in text one line at a time
                    LayerRef = docRef.artLayers.add();
                    LayerRef.kind = LayerKind.TEXT;
                    TextRef = LayerRef.textItem;
                    TextRef.contents  = textLine;
                    //optional text styling, can be customized to suit
                    pos = pos + 50;
                    TextRef.position = new Array(pos, pos);
                    preferences.rulerUnits = Units.POINTS;
                    TextRef.size = 24;
                    TextRef.useAutoLeading = false;
                    TextRef.leading = 24;
                    TextRef.font = 'Calibri-Bold';
                    TextRef.justification = Justification.CENTER;
                    TextRef.autoKerning = AutoKernType.METRICS;
                    //end optional text styling
                    textLine = testFile.readln();
                    }
                testFile.close();
                }
            }
        catch(e){
            alert(e + e.line);
            preferences.rulerUnits = originalRulerUnits;
            app.displayDialogs = originalDialogMode;
            return;
            }
        preferences.rulerUnits = originalRulerUnits;
        app.displayDialogs = originalDialogMode;
        }
    else{
        alert('You must have a document open to run this script.');
        return;
        }
    return;
    }

I have a number of scripts that do things with CSV data, for Photoshop and other apps, but not any published yet that do precisely what you describe. It is certainly possible. The one Photoshop script of mine that is close is described in this video: https://youtu.be/zsaVUHEi6X0

I have two other scripts in progress at this time for some clients that work on multiple text layers from multiple CSV columns. Nothing that creates the layer, but that's not a big deal. The scripts I've made the clients had the layer already because they wanted to style it with effects. That's a good reason to have a layer exist already. I do custom scripts for hire to exact client needs. If interested message me through my website http://www.marspremedia.com/contact/

Photoshop has a built in Variable feature to populate existing text placeholder layers with content from a comma or tab delimited text file.

Otherwise, yes, a script can read from the .csv and create a text layer and content.

It would be helpful if you could provide sample files or before and after screenshots to illustrate, as there are more questions than answers at the moment.
