Unless you already understood:
su - "make the shell a login shell"
so sudo -l in bashrc is executed, which asks for the user's password

Understood, who is asking - not understood why "sudo -l" is asking for
the password and why just hitting the enter key works

Hitting the enter key "works" as far as making the prompt go away, but
the sudo command is actually failing silently. If you enter the correct
password, you should receive some extra output.
Just pressing enter at the prompt:
$ sudo -l
Password:
$
Entering the correct password:
$ sudo -l
Password:
User xxxxxx may run the following commands on this host:
(ALL) ALL
$

sudo -l
lists the commands that you are allowed to run with sudo

That is clear to me, but why does this command request the password?

Security?
Maybe they don't want someone passing by to find out what this user can run through sudo...

Do you have rootpw/runaspw/targetpw set in /etc/sudoers?

No, I don't have. What I want to have is: None-root users shall be
allowed to run some commands as root whithout password. And, on logging
on, the users shall see, what commands they are able to run.
Thanks,
Uwe
