This sounds trivial but I can't seem to place the helptext right besides the radio button field, if you check this demo you see there is a big gap.

I tried to use grids and custom padding but nothing seems to work, unlike the lightning-input there is no built-in help text attribute per the documentation.

You defined a flex-box with two column and put the help text on the second one, that's why there's a lot of space between it and the radio buttons. Docs

  1. Add a grid container by adding slds-grid to an HTML element
  2. Add as many slds-col elements as you want inside of your grid container
    Initially, each column takes an equal percentage of the width available.

The column that contains the radio buttons could be a flex-box too (slds-col slds-grid), then you have to simply put the help text next to the radio button (I left the second column):

    <div class="slds-grid slds-gutters slds-var-p-vertical_medium">
        <div class="slds-col slds-grid">
                    label="Radio Group"
                <lightning-helptext content="test"></lightning-helptext>
        <div class="slds-col">
            Col 2
