You can create a list (element <text:list>) without setting a list style. Then
an implementation-dependent list style is used. LibreOffice currently uses a
bulleted list in such cases.
I never would go that way, because it has huge interoperability consequences. 

A list style is given by the <text:list-style> element. Either of the child
elements <text:text:list-level-style-number> or <text:list-level-style-bullet>
or <text:list-level-style-image> must exists. Something else is not possible. 

The bullet character is defined in the `text:bullet-char` attribute of the
<text:list-level-style-bullet> element. This attribute is mandatory. That
means, that a bullet list without specifying a bullet character is not
possible.
https://docs.oasis-open.org/office/OpenDocument/v1.3/os/schemas/OpenDocument-v1.3-schema-rng.html#text-list-level-style-bullet-attr

But since U+20 SPACE or U+200B ZERO WIDTH SPACE or any other space character
works as "bullet" I see no problem. The use case "programmatically" is not
common, thus we can expect an advanced user. And for screen readers, it would
need a test, whether they say anything about the bullet character or whether
they report only the list level.

The spacing is not defined by the bullet character, but by the settings in tab
"Position". It can be changed there, same as for any other list.

I do not support this enhancement request.
