Thanks to the link from Opal in the comments, I found a solution. The link shows that it is possible to have multiple from sources and each of these can have a separate expand treatment. Thus, in my case, I only wanted to expand .txt files, so I split the from into two parts using include & exclude as follows:

task "copyAndroidAssets$flavor" (type: Copy, 
    dependsOn: ["cleanAndroidAssets", "copyAndroidRes$flavor"] ) {
    from ("build/assets/${flavorLc}/release/") {
        include '**/*.txt'
        expand ( versionName: versionName, versionCode: versionCode )
    }
    from ("build/assets/${flavorLc}/release/") {
        exclude '**/*.txt'
    }
    into '../android/assets'
    expand ( versionName: myVersionName, versionCode: myVersionCode )
}
