You can try the command pwdck, but it only reports if there is a valid entry in /etc/passwd. As the other information you have found states, you can only see if there is an entry in the /etc/security/passwd for the user in the parameter "password" like password = uo34giu34hg. An empty entry has no password set.

You have no /etc/shadow on your system because AIX doesn't use it. This is usually a file being used on Linux and maybe some other Unix'es. It uses files like /etc/security/passwd and /etc/security/user etc. with similar functionality.
I don't see any problem in checking this file for entries. The tools do the same.

pwconv

pwconv(1M)                                                System Administration Commands                                                pwconv(1M)

NAME

       pwconv - installs and updates /etc/shadow with information from /etc/passwd

SYNOPSIS

       pwconv

DESCRIPTION

       The pwconv command creates and updates /etc/shadow with information from /etc/passwd.

       pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is
       already in /etc/shadow and should not be modified.

       If the /etc/shadow file does not exist, this command will create /etc/shadow with  information  from  /etc/passwd.  The  command  populates
       /etc/shadow  with  the  user's  login  name,  password,  and  password  aging  information. If password aging information does not exist in
       /etc/passwd for a given user, none will be added to  /etc/shadow. However, the last changed information will always be updated.

       If the  /etc/shadow file does exist, the following tasks will be performed:

                Entries that are in the  /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file.

                Entries that are in the  /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow.

                Password attributes (for example, password and aging information)  that exist in an /etc/passwd entry will be moved to the  corre-
                sponding entry in  /etc/shadow.

       The pwconv command can only be used by the super-user.
