You can hide the text, but that doesn't seem like a great solution, as the icons are also reversed unless you choose a non RL language.
To hide the text, right-click on a blank space and select "Appearance>Hide icon text." You will have to do this on a Group basis, so you will have to perform this procedure for each Group individually.
When you right-click in Start11, are the context menus in Hebrew or English?
Also, I found this thread from July of 2023 of someone else with the same issue, so I know Stardock is aware of the RL language issue.

And this thread on changing the language for Start11.

Hope some of this helps you.
