The old dishwasher was hardwired using FLEX connected to 1/2" EMT sticking out of the wall close to floor. The new dishwasher does not offer hardwire. There is a junction box accessory available. However, it doe snot fit behind dishwasher. The box is meant to go inside sink cabinet. This is not an option on this project.

I believe a handy box could fit. Using a cord grip connector like this:

Sigma Engineered Solutions | Cord Grip Connector

Strain relief cord grip connectors are used to connect S, SO, ST, SJ, SJO and SJT cord to an outlet...
sigmaengineeredsolutions.com sigmaengineeredsolutions.com

However, I was wondering whether I could make this even more compact with a LB body.

1.) use a combination LB body (EMT and rigid): https://nsiindustries.com/product/type-lb-combination-conduit-body-with-cover-and-gasket-1-2/
2.) grip connector

Connecting wires in LB body. Which I know is not commonly done, but I believe it is allowed?

The LB will be marked with a volume and the box fill rules in 314.16 apply to connections made in a conduit body. I doubt that a 1/2" conduit body has the required volume for the splices.

probably would get tight to get to the 4 cu inch required for a 14AWG splice

There are some larger bodies like this combo from Arlington:

Arlington | 930 Product Information

Copper free aluminum die-cast. five conduit bodies in one. Ships as an LB but converts to a T, LL, LR, or C. Combination threaded IMC or Rigid and set screw EMT. Trade Size 1/2

What do you mean by the dishwasher not offering hardwire? Is there a cord and plug on it from the factory?

There is a factory cord that plugs into the front (behind toe kick) and a regular plug for receptacle:

They also offer a junction box as an accessory that woudl work to hardwire. The problem with this is that it does not fit behind dishwasher

Similar, I don't think I have enough space for a surface or floor mounted receptacle.

So, I am looking for a space saving solution. So, I would cut 5-15 plug.
 
We used to put a switch in a 1900 box with NM in and out and leave it behind the kick panel for a disconnect. Looks like you can do that with that junction box kit. Stick it under there wherever it will fit under the machine.

no, the cut cord to the EMT tube

No, you can't do that. You can't cut a plug off a line cord and wire it directly to a box. That's why they have the junction box kit. Connect the flex to the box and plug the cord from it into the dishwasher. That box can go on the floor under the machine; it doesn't have to be fastened or in the cabinet next to the dishwasher.

That junction box kit is already done for you- isn't that what you are trying to do by jury rigging that stuff?
