You can use axis guides to draw single lines beneath the chart. E.g.

var range = dateAxis.axisRanges.create();
range.date = new Date("2016-03-14");
range.grid.stroke = am4core.color("red");
range.grid.strokeWidth = 2;
range.grid.strokeOpacity = 1;

If you need a line on top of the various series, what you can do is make a full height line (y1, y2 at 0, not sure how to get the top of the chart value... says it only takes numbers meaning pixels, but maybe it can work with am4core.percent(100)?), for its x you'll have to convert date to a coordinate on the chart (the dateAxis will probably have methods for that), and place it in the chart.plotContainer.
