I am trying to figure out if and how I can create a select by attributes tool for a map service within ARCGIS Online, since the tool is not available on that program. I was wondering if there is a script I could run in the API that would do this, or if I could somehow incorporate python script into ARCGIS Online, since I know the python code to run a selection by attributes.
Two things come to mind. In #8 of this thread, you mention uploading data from ArcMap to AGOL using "Add Layer from File". I'm not sure what that means. Try pushing your ArcMap data to AGOL via >File >Share As >Service. The result will be a Hosted Feature Service.

Secondly, not every layer "Type" in the table-of-contents of an AGOL map is able to have its attribute table exposed or filtered. See my capabilities table, below.
