Double nods to Phil B. and Zhaph - Ben Duguid ♦ for offering correct answers, but Mark Thrill has provided further detail that might be a program issue, or he might have just said these words in jest.
"I've been looking for it for hours on LDD..."
We know that certain versions of LDD do exclude pieces. The version of LDD that I'm using does have both ...
There are two variant of that, which look very similar:
Stud.IO lists them as:
Brick, Modified 2 x 4 - 1 x 4 with Recessed Studs and Thick Side Arches
Brick, Modified 2 x 4 - 1 x 4 with Recessed Studs and Thin Side Arches
These can be seen below, thick in red on the left, and thin in blue on the right in the top picture (not a valid colour):
This pieces is indeed hard to find, as it is used in building vehicles but does not have a name that has anything to do with that purpose. It is part number 52038 and is called Brick, Modified 2 x 4 - 1 x 4 with 2 Recessed Studs and Thick Side Arches on Bricklink.
Quoting from Lego's LDD page:
Sorry. We don’t support LDD version 4.3.10 anymore.
If you still use version 4.3.10 you will experience errors when launching the application.
You can still use “offline” mode if you wish.
We urge you to update, use the download link, and install free application for Windows PC & Mac OSX.

The option furthest back is where you use a 1x1 brick with side stud and a tile in the corner. You could alternatively replace one of ...
Here's an attempt at what I think you might mean, an offset wall that turns a corner while somewhat maintaining it's aesthetically balanced negative space between the bricks.
I'll upload the build file, if this is what you're looking for.
(Of, course we're focusing on the wall not Picasso's Junk Lighthouse behind it.)

Brinklink offers two programs that could be right up your alley:
Studio 2.0 - A popular alternative to LEGO Digital
I've come up with five different ways to make a micro security camera that look like your reference image.
I'll run through the different methods in the image above from left to right 1 through 5.
Far left camera 1
Tile, Round 1 x 1 in black (the lens), Brick, Round 1 x 1 Open Stud in white (camera body), Plate, Modified 1 x 1 Rounded with Handle in white ...
The kinds of software used to design LEGO MOC doesn't necessarily have to be solely confined to Computer Aided Design programs.
We can get really creative and exploit functions of programs never intended to be used for MOC bricking.
Enter: Adobe Photoshop - PS's main role is a visual graphic editor, but it does something strange if an image is magnified ...
