The first issue is the choice of base component type here. An oh-list-card is expecting specific items as it’s children: list items. So while you can render other thing such as the oh-label-card within the list, the results are not necessarily going to be what you expect. In this case, you probably just want a more basic starting component such as an f7-card or f7-block.
Most of the other issues are with this line here:
The yaml definitions interpret all inputs as strings unless you explicitly define them as expressions using the = at the front. So, in this case you are not setting the input array to your JSON text you are setting it to the literal string "items[14_Entry_Users]".
To access the keys in the items object using the bracket notation, your item name must be a string. It can either be a variable that holds a string value or if its a literal string then it needs " around it.
Here in the widgets, the items object has both .state. and .displayState properties, so you have to specify which you want at all times. In this case I assume you want the raw .state.
Taken together then, this line should probably be:
