I have multiple coordinates in one field which represent a geofence or a polygon of influence. How do I plot these points ? XY to Point allows just one. The image below shoes the coordinates represented as lat/long. Is there a way I can automate this or is there a particular tool?
You can create and add geometries to a feature class in Python using an Insert Cursor:

See the last code example, at the bottom of the page, for how to do this for polylines.

Or, if you reformat your data a bit, you might use this tool:
