"literally hundreds" should not be happening. A few dozen up close to
100 is normal.

It is entirely possible though if you are intercepting the clients
traffic, have a browser doing "Happy Eyeballs", lots of plugins and/or
tabs being started, and loading detailed pages like Facebook or CNN.
 The connection numbers involved there can multiply up to big values.

debug_options 11,2 in squid.conf will log the HTTP messages flows as
they arrive. That might give hints. Check for Connection:keep-alive vs
Connection:close on the mesages between Squid and the browser/client.
