Actually I'm doing something similar. I want English for everything, 
except the date on desktop apps. For the terminal, I want en_US date format.

You can configure your desktop environment to use the format you want. 
For KDE 5, this is configured in System Settings -> Regional Settings -> 
Formats. Like this:

For login shells (meaning terminals, including virtual consoles), I 
override the stuff (LANG and LC_* variables.) This is done in ~/.bashrc 
(or whatever file is ONLY sourced for login shells on your system.) For 
doing this for all users, you would use /etc/bash/bashrc (or perhaps put 
a new file in /etc/bash/bashrc.d/).

In your case, you would set "Region" to what you want in the KDE 
configuration. The "Detailed Settings" checkbox should be left 
unchecked. Then, in your ~/.bashrc (or the global login shell config in 
/etc), you would use:

   export LANG="en_US.UTF-8"

That means applications will use your System Settings configuration, 
except terminals/consoles.

Since you're using KDE4, you need to do this in your KDE4 System 
Settings, not the KDE5 one, since the setting is applied by your Plasma 
4 session. KDE5 applications should follow it regardless (as will Gtk 
and Gnome applications.)
