Question

You can use below code to display theme detail sentence. I have use wp_footer action,You can change hook as per your requirement.

function logbook_info() {
    $theme_logbook = wp_get_theme();
    $theme_name = esc_html( $theme_logbook->get( 'Name' ) );
    $theme_uri = esc_html( $theme_logbook->get( 'ThemeURI' ) );
    $theme_author = esc_html( $theme_logbook->get( 'Author' ) );
    $theme_author_uri = esc_html( $theme_logbook->get( 'AuthorURI' ) );

    $theme_html="<a href="".$theme_uri.'">'.$theme_name.'</a>';
    $author_html="<a href="".$theme_author_uri.'">'.$theme_author.'</a>';

    echo "The ".$theme_html." developed by ".$author_html;
}
add_action( 'wp_footer', 'logbook_info' );
