paracol and lettrine - problems with small paragraphs

If I use lettrine inside a paracol environment and parindent is set to 0mm, the following problem arises if the paragraph on both sides is just one line:

There is no indentation in the next line and the text is overlapping with the text of lettrine.

How can I detect the paragraphs that consists of just one line and automatically add the needed indentation for the next paragraph? (Lettrine is used about 2000 times in documents with different page width, manual adjustment is not an option.)

    documentclass[a5paper,twoside]{article}
    usepackage{geometry}
    usepackage{paracol}
    usepackage{lettrine}
    
    setlength{columnsep}{3mm}
    setlength{parindent}{0mm}
    
    begin{document}
    
    begin{paracol}{2}
    switchcolumn[0]
    
    lettrine{1}
    Not much text
    
    switchcolumn
    
    lettrine{1}
    And again
    
    switchcolumn*
    
    Some text
    Some text
    Some text
    Some text

    switchcolumn
    
    Some other text

    switchcolumn*
    
    lettrine{2}
    Some text
    Some text

    Some text
    Some text
    Some text

    Some text
    
    switchcolumn
    
    lettrine{2}
    Some other text
    Some other text
    Some other text
    Some other text
    Some other text
    Some other text
    Some other text
    
    switchcolumn*
    
    end{paracol}
    
    end{document}

As @John Kormylo pointed out, this is not a problem of paracol.

My solution, based on his answer, is as follows:

documentclass[a5paper,twoside]{article}
usepackage{geometry}
usepackage{paracol}
usepackage{lettrine}
usepackage{lipsum}

setlength{columnsep}{3mm}
setlength{parindent}{0mm}

newlength{CLFL}% Custom length for lettrine
newlength{IFLL}% Indentation for lettrine left
newlength{IFLR}% Indentation for lettrine right
setlength{IFLL}{0pt}
setlength{IFLR}{0pt}

makeatletter
newcommand{lettrineLeft}[2]% #1=letter, #2=paragraph
{bgroup
    setbox0=vbox{lettrine{#1}{}{globalCLFL=dimexpr L@height-L@lraise-htstrutbox} #2}%
    setlength{@tempdima}{dimexpr CLFL-ht0-dp0}
    ifdim@tempdima> -10pt
    setbox0=hbox{lettrine{#1}{}{[email protected]}}
    fi
    egroup
    lettrine{#1}{} #2}

    ifdimIFLL> 0pt
    ifdim@tempdima> -10pt
    setbox0=hbox{lettrine{#1}{}{[email protected]}}
    fi
    else
    globalsetlength{IFLL}{0pt}
