Not sure why this could be a problem, but in a basic demo you can just use some Trigger listening to IsReadOnly and set the Border for the TextBox normally:

<TextBox IsReadOnly="True"  BorderThickness="1">
    <TextBox.Style>
       <Style TargetType="TextBox">
          <Style.Triggers>
             <Trigger Property="IsReadOnly" Value="True">
                <Setter Property="BorderBrush" Value="Blue"/>                    
             </Trigger>
          </Style.Triggers>
       </Style>
    </TextBox.Style>
</TextBox>

The above example sets the IsReadOnly to true initially, so some Blue border will be shown.

Update:

for the code you posted, it should be like this:

<Style TargetType="TextBox" x:Key="StandardTextBox">
  <Style.Resources>
    <fawgCommon:ControlBackgroundConverter x:Key="BackgroundConverter" />
  </Style.Resources>
  <Style.Triggers>
     <Trigger Property="IsReadOnly" Value="True">
         <Setter Property="BorderBrush" Value="Blue"/>
         <Setter Property="BorderThickness" Value="1"/>
     </Trigger>
  </Style.Triggers>
  <Setter Property="telerik:StyleManager.Theme" Value="{DynamicResource Theme}"/>
  <Setter Property="Background">
    <Setter.Value>
        <MultiBinding Converter="{StaticResource BackgroundConverter}">
            <Binding />
            <Binding Mode="OneTime"/>
        </MultiBinding>
    </Setter.Value>
  </Setter>
  <Setter Property="Foreground" 
          Value="{DynamicResource CurrentThemeForegroundBrush}" />
  <Setter Property="CaretBrush" 
          Value="{DynamicResource CurrentThemeForegroundBrush}" />
</Style>
